In terms of performance and portability, portable electronic devices have also sought to increase the energy density of batteries used. Therefore, a secondary battery which is both lightweight and high in capacity is required. For the requirements of such secondary batteries, for example, lithium ion batteries have been developed. In addition, the operation time of carrying an electronic device has increased. In the lithium ion secondary battery, the increase in the density of the material from the viewpoint of the material and the structure is almost reaching the limit, and thus it is gradually unable to meet the demand. Φ Based on such a situation, a small-sized fuel cell has attracted attention as a replacement for lithium ion secondary batteries. In particular, a direct methanol battery (DMFC) using methanol as a fuel is more difficult than minimization because it has no difficulty in hydrogen gas and does not require a device for changing hydrogen production from organic fuels.

On the other hand, in the country 112172A1, by supplying a reaction to the cathode proton conductive membrane for the anode, it is intended to increase the output characteristics when the liquid is added. The fuel cell described in the above-mentioned Japanese Patent No. 3 4 1 3 1 1 1 or International Publications can be obtained as a sub-unit of a fuel cell or a fuel cell, which is small and high, and is exported by being shipped and distributed on the market. There are concerns about reduced features.

Further, various inventions can be formed by appropriately combining a plurality of constituent elements described in the following embodiments. For example, a plurality of constituent elements may be deleted from all of the constituent elements shown in the embodiment. Furthermore, it is also possible to appropriately combine the constituent elements between the different embodiments. In Fig. 1, a container for a fuel cell according to an embodiment of the present invention is shown in a mode. As shown in Fig. 1, the container 1 has a rectangular tube shape, and the surface of the circular vent hole 2 is mostly open.

There is no restriction on the composition of the fuel cell that can be introduced into the fuel cell. The opening ratio of the container 1 is preferably 50% or less. Since the strength of the container 1 may be insufficient when the opening ratio exceeds 50%, in addition, φ leakage may occur during transportation. Further, in order to sufficiently control the decrease in output due to transportation and storage, the opening ratio is preferably 10% or more. A better range is 30 to 50%. By setting it within this range, the output characteristics that are unchanged before the transfer and storage can be realized. The material forming the container 1 may, for example, be paper, hard resin, foamed resin, rubber 'fiber, metal, leather, and a combination of these plural materials. The fuel cell 3 is housed in the container 1 at the time of shipment, during market distribution, or when it is carried. The type of the fuel cell 3 is not particularly limited, and is preferably a fuel cell fuel supply method in which an anode is supplied with a vaporized fuel, and a fuel cell in which a water supply method of a water generated by a cathode is supplied to a cathode.

Examples of the cathode catalyst and the anode catalyst include monomer metals such as platinum group elements (?1, 1111, 1111, 1]*, 〇3, ?(1, etc.), alloys containing a platinum group element, and the like. Cathodic catalyst Although it is preferable to use platinum, it is not limited to this. In the anode catalyst, Pt-Ru' which is highly resistant to formaldehyde and carbon monoxide is preferably used, but is not limited thereto. Further, for example, a carbon material can be used. The carrier catalyst of the conductive carrier may be a carrier-free catalyst. -9- 200810195 (6) Proton conduction contained in the cathode catalyst layer 6a, the anode catalyst layer 7a, and the proton conductive electrolyte membrane 8 As the material, a fluorine-based resin having a sulfonic acid group such as a fluorocarbonsulfonic acid, a hydrocarbon-based resin having a sulfonic acid, an inorganic substance such as tungstic acid or phosphotungstic acid, or the like can be used. - Cathode catalyst layer 6a is laminated. In the anode gas diffusion layer 6b, the anode-electrode catalyst layer 7a is laminated in the anode gas diffusion layer 7b. The cathode gas diffusion layer 6b has a function of uniformly supplying the oxidant gas to the cathode catalyst 6a. The diffusion layer 7b is uniformly supplied to the anode catalyst 7a. For the cathode gas diffusion layer 6b and the anode gas diffusion layer 7b, for example, porous graphite paper can be used. The anode conductive layer 9 as an anode current collecting portion is laminated in the anode gas diffusion layer 7b of the membrane electrode group 5. On the one hand, the cathode conductive layer 10 as the cathode current collecting portion is laminated in the cathode gas diffusion layer 6b of the membrane electrode group 5. The anode conductive layer 9 and the cathode conductive layer 10 improve the conductivity of the cathode and the anode. Further, the anode conductive layer 9 and the cathode conductive layer 10 are opened by the oxidant gas or the vaporized fuel so that there is a gas permeation hole (not shown). The anode conductive layer 9 and the cathode conductive layer 1 are, for example, A gold electrode carrying Au foil can be used in the PET substrate. ~ One side of the rectangular frame-shaped sealing material is 1 1 a, which is formed on the proton conducting electrolytic membrane 8 as if it is around the cathode.

較陽極觸媒層7a之水分保持量多之狀態。其結果藉由浸 透壓現象，可促進陰極觸媒層6a中生成水通過質子傳導 性膜8後移向陽極觸媒層7a之反應。據此，可實現小型 且高輸出之燃料電池。 收容燃料電池之容器，並不限定於前述圖1所示構造 之物，可使用例如圖3所示之篩孔板所形成，將其網眼作 爲通氣孔2使用之容器1。此外，容器之形狀，不限於如 圖1及圖3之四角筒形狀，可爲如圖4所示之袋狀、圖5 所示之圓筒形狀。

fuel tank 1 2 of the fuel storage unit. The liquid fuel tank i 2 contains a liquid fuel 13 made of liquid formaldehyde or an aqueous formaldehyde solution. The concentration of the bow liquid is preferably a high concentration of more than 50 mol%. Further, the turning purity ' is preferably 95% by weight or more and 1% by weight or less. The liquid fuel contained in the fuel tank 12 is not limited to a glycol fuel such as an ethanol solution or a pure ethanol, a propanol fuel such as propanol, a glycol aqueous solution, and a pure ethylene glycol. Such as fuel, dimethyl ether, citric acid, or other liquid fuels may also be used. The tank contains the liquid fuel of the corresponding fuel cell. Further, when the fuel cell is housed in the container 1, although the liquid combustion is preferably in a state of being empty, the fuel is not in a state of being filled. When the fuel is empty, occasionally the liquid fuel tank 1 2 4 is a small amount of liquid fuel 13 , and the output reduction can be further reduced. Of course, the pool is replenished with liquid fuel 13 before it is taken out of the container 1. Between the liquid fuel tank 12 and the anode, a gasification fuel supply method for supplying a liquid fueling component to the anode, for example, a membrane 144 is disposed. The gas-liquid separation membrane 14 is a membrane that only makes the liquid fuel vaporize and the liquid fuel does not. In the liquid fuel, only the gas # is passed through the gas separation membrane 14 so that the vaporized fuel can be supplied to the anode. In the film 14, a water-repellent film such as a formaldehyde-permeable film can be used. The water-repellent film which is adjusted, such as a ruthenium plate, a polyethylene porous film, a porous film, a polyethylene-polypropylene porous film, a porous polytetrafluoroethylene porous gas separation membrane 14 and an anode conductive layer 9 may be arranged. 15 15a surrounded by space, with a gasification fuel supply adjusted to the anode, 3 aldehyde water soluble & formaldehyde, liquid I fuel, sputum and pure: ethylene glycol I, the receiving tank 12 Γ ask For example, the gasification of the fuel gas f is separated by the liquid separation. The S component is permeated: the component is permeated through the liquid L to separate the k-formaldehyde and the polypropylene. a. In the case of the frame ί - -11 - 200810195 (8) The function of the gasification fuel containment chamber 16. Further, the cathode conductive layer 1 of the membrane electrode group 5 is laminated to the frame 15b. The laminate in the cathode catalyst layer 6a on the frame 15b suppresses the formation of water evaporation by the moisturizing plate 1 7 ° moisturizing plate 17 with the function of supplying water to the anode for supplying water to the anode. * Moisture plate 17 is preferably formed of an insulating material that is inactive, resistant to solubility, oxygen permeability, and moisture permeable to formaldehyde. Examples of the insulating material ^ include polyolefins such as polyethylene and polypropylene. The moisturizing plate 17 is preferably a gas permeability of 50 sec/100 cm3 or less as defined in JIS P-8 1 1 7- 1 998. When the air permeability exceeds 50 sec/100 cm3, the air diffusion from the air introduction port 18 to the cathode may be hindered and the central output may not be obtained. A more preferable range of air permeability is 10 seconds/l〇〇cm3 or less. 保湿 The moisturizing plate 17 is preferably the permeable humidity of 6000 g/m224h or less as defined by JIS L-10099-1993 A-1. Further, the above-mentioned number of moisture permeability • ' is as shown in the measurement method of JIS L-10 "- 1 993 A-1, and the temperature is 40 ± 2 ° C. When the moisture permeability exceeds 6000 g/m 224 h, the evaporation amount of water from the cathode increases, and the effect of promoting the diffusion from the cathode to the anode water may not be sufficiently obtained. In addition, when the moisture permeability is less than 500g/m224h, excessive water may not be obtained after the water is supplied to the anode, and the moisture permeability is preferably in the range of 500 to 6000 g/m224h. A more preferable range of the moisture permeability is 1 000 to 4000 g/m 224 h. The outer container 4 is formed on the surface opposite to the moisturizing plate 17 to form a plurality of air introduction ports 18. The outer container 4 has an effect of increasing the adhesion of the rod-containing 12-121010(9) of the membrane-containing electrode group 5, for example, SUS304, carbon steel, stainless steel, alloy steel, titanium alloy, A metal formed of a nickel alloy. The liquid fuel 13 in the liquid fuel tank 12 is supplied to the anode catalyst layer 7a through the gas-liquid separation membrane 14 after the vaporization component thereof. In the anode catalyst layer 7a, protons (H+) and electrons (e-) are generated by oxidation reaction of the fuel. For example, when formaldehyde is used as the fuel, the catalytic reaction generated in the anode catalyst layer 7a is as shown in the following formula (1). CH3OH + H20-> C〇2 + 6H + + 6e- (1) Protons (H+) generated in the anode catalyst layer 7a diffuse through the proton conductive membrane 8 and then to the cathode catalyst layer 6a. Further, at the same time, the electrons generated by the anode catalyst layer 7a flow into the cathode circuit layer 6a in the external circuit of the fuel cell to the subsequent external circuit for the load (resistance, etc.) of the external circuit. The oxidant gas such as air is supplied from the air introduction port 18 of the outer container 4 to the cathode catalyst layer 6 &; The oxygen of φ in the oxidant gas undergoes a reduction reaction with a proton (H+) diffused through the proton conductive membrane 8 and an electron (^) flowing to the external loop to form a reaction product. For example, when air is used as the oxidant gas, the reaction of the oxygen contained in the air in the cathode catalyst layer 6a is as shown in the following formula (2), and the reaction product is water (H20). 1.502 + 6H + + 6e'^ 3H2〇 ( 2 ) By the simultaneous reaction of the formulas (1) and (2), the power generation reaction as a fuel cell can be completed. The total fuel reaction is as shown in the following formula (3) -13 - 200810195 (10) CH3OH + 1.502 - C〇2 + 2H20 (3) Between the cathode and the outer container 4, the moisture plate 17 is arranged to suppress evaporation of water from the cathode. The amount of moisture retention of the cathode catalyst layer 6a increases as the power generation reaction proceeds. Therefore, a state in which the amount of moisture retained by the cathode catalyst layer 6a is larger than that of the anode catalyst layer 7a can be generated. As a result, by the impregnation phenomenon, the reaction of the generated water in the cathode catalyst layer 6a through the proton conductive membrane 8 and then to the anode catalyst layer 7a can be promoted. According to this, a small and high-output fuel cell can be realized. The container for accommodating the fuel cell is not limited to the structure shown in Fig. 1, and can be formed, for example, by using a mesh plate as shown in Fig. 3, and the mesh is used as the container 1 for the vent hole 2. Further, the shape of the container is not limited to the rectangular tube shape as shown in Figs. 1 and 3, and may be a bag shape as shown in Fig. 4 or a cylindrical shape as shown in Fig. 5. In the container for accommodating the fuel cell, a detection method for detecting the oxygen concentration in the container may be provided to detect a decrease in the oxygen concentration in the container. In addition, a humidity control mechanism is provided in the container to maintain a certain humidity in the container. Furthermore, a mandatory air absorbing mechanism can be provided after detecting an increase in humidity. Further, the container for accommodating the fuel cell can be applied to one or a plurality of containers for accommodating the fuel cells, and can be applied to a storage container as a container for accommodating a plurality of the containers. In the above description, the container for accommodating the fuel cell 3 will be described. However, the present invention can also be applied to an electronic device in which the fuel cell 3 is mounted. In short, the electronic equipment equipped with a fuel cell can be used for shipments, packaging, etc., which are carried out on the market, and which are sold in the market, and which are used to store and store the packaging containers, and to accommodate a plurality of containers of the packaging containers. . Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. [Embodiment] (Example 1) A direct formaldehyde fuel cell shown in Fig. 2 was produced as follows. The platinum particles were loaded with platinum particles and a DE2020 manufactured by Dupont Co., Ltd., and mixed in a homogenizer to form a slurry, which was applied to graphite paper of the cathode gas diffusion layer 6b. Next, this is dried at normal temperature, and a cathode of the laminated cathode catalyst layer 6a is formed on the cathode gas diffusion layer 6b. The graphite particles containing the platinum bismuth alloy fine particles and the DE 2020 manufactured by Dupont Co., Ltd. were mixed with a homogenizer to prepare a slurry, which was applied onto the graphite paper of the anode gas diffusion layer 7b. Next, this is dried at normal temperature, and an anode of the laminated anode catalyst layer 7a is formed on the anode gas diffusion layer 7b. As the proton conductive electrolyte membrane 8, perfluorocarbonsulfonic acid (nafion (registered trademark) membrane, manufactured by Dupont Co., Ltd.) having a thickness of 30 μm and a water content of 10 to 20% by weight was prepared. This electrolyte membrane was sandwiched between a cathode and an anode, and pressed at a temperature of 120 ° C under a pressure of 10 kgf/cm 2 to prepare a membrane electrode assembly (MEA) 5 . Next, the membrane electrode assembly 5 is sandwiched by a plurality of openings having a absorbing air and vaporized formaldehyde in a gold foil to form a cathode conductive layer 1 and an anode conductive layer 9 〇 the membrane electrode assembly (MEA) 5, an anode conductive Layer 9, Cathode Conductive Layer 200810195 (12) The 10 laminated laminate was sandwiched between two frames 15a, 15b made of resin. Further, between the cathode side of the membrane electrode group 5 and the frame 15b of the other side, between the anode side of the membrane electrode group 5 and the frame 15a of the other side, each of them is placed in a rubber-made 0 shape. Circle 1 1 a, 1 1 b and seal. Further, the frame 15 5 a on the anode side is screwed to the liquid fuel tank 12 by the gas-liquid separation film 14 . A 0.1 mm thick sand plate was used in the gas-liquid separation membrane 14. As a moisturizing plate, the thickness is 500 μm, the air permeability is 2 seconds/100 cm3 (JIS Ρ-8 1 1 7- 1 998), and the moisture permeability is 4000 g/m224h (JIS L-1 09 9-1 9 93 A-1 method) Polyethylene porous membrane. A moisturizing plate 17 is disposed on the cathode side frame 15b. The obtained laminate was formed into an external container 4 by a stainless steel plate (SUS 3 04) having a thickness of 2 mm, which was formed into an air inlet port 18 for air introduction (having a diameter of 2.5 mm and a port number of 8). Direct formaldehyde fuel cell shown. The obtained fuel cell was stored in the container 1 of the shape shown in Fig. 1 in the state in which the liquid fuel tank 12 was charged. Further, the material of the container was made of a resin material (polyethylene terephthalate) and the opening ratio was 50%. The storage conditions were 30 hours at 30 ° C and 50% relative humidity for 48 hours. After the storage, the fuel cell was taken out from the container 1, and 5 ml of pure formaldehyde was injected into the liquid fuel tank 12 as the liquid fuel 13. The power density and the cell voltage at the time of increasing the current density were measured under an environment of a temperature of 25 ° C and a relative humidity of 50%. The result is taken as the output density change curve A1, and the battery voltage change is taken as the curve B1 as shown in Fig. 6. The horizontal axis of Fig. 6 is current density -16 - 200810195 (13) (mA/cm2), the vertical axis on the right side is the output density (mW/cm2), and the vertical axis on the left side is the battery voltage (V). (Example 2) * A fuel cell produced in the same manner as described in the first embodiment will be described. The obtained fuel cell is stored in the container 1 having the shape shown in Fig. i in the state in which the liquid fuel tank 12 is filled. In the container 1, the same thing as in the first embodiment was used except that the opening ratio was 30%. The storage conditions were the same as in Example 1. After the storage, the fuel cell was taken out from the container 1, and the same liquid fuel 13 as in Example 1 was injected into the liquid fuel tank 12. Next, the output density and the battery voltage were measured in the same manner as in the first embodiment. The result is taken as the output density variation curve A2, and the battery voltage change is taken as the curve B2 as shown in Fig. 6. (Example 3) A fuel cell was produced in the same manner as described in Example 1, and the obtained fuel cell was stored in the container 1 of the shape shown in Fig. 1 in the state in which the liquid fuel tank 12 was filled. In the container 1, the same thing as in Example 1 was used except that the opening ratio was 10%. The storage conditions were the same as in Example 1. After the storage, the fuel cell was taken out from the container 1, and the same liquid fuel 13 as in Example 1 was injected into the liquid fuel tank 12. Next, the output density and the battery voltage were measured in the same manner as in the first embodiment. The result is taken as the output density variation curve A3, and the battery voltage change is taken as the curve B3 as shown in Fig. 6. The output density change of Fig. 6 is as shown by Al, A2, and A3, and the maximum output density increases as the opening ratio of the container 1 in which the fuel cell is housed increases. -17- 200810195 (14) The maximum output density of Examples 1 and 2 having an opening ratio of 30 to 50% is particularly preferable to Example 3 having an opening ratio of 10%. Further, as the battery voltage changes as indicated by B1, B2, and B3, the decrease in the battery voltage at the time of increasing the current density decreases as the opening ratio of the container '1' in which the fuel cell is housed increases. The voltage characteristics of Examples 1 and 2 having an opening ratio of 30 to 50% are particularly preferable to Example 3 having an opening ratio of 10%. (Comparative Example) A fuel cell produced in the same manner as described in the first embodiment will be described. The obtained fuel cell is stored in a gas-tight container without a vent hole in a liquid fuel tank 12 state. The storage conditions were the same as in Example 1. After the storage, the fuel cell was taken out from the container, and the liquid fuel 13 was replaced in the liquid fuel tank 12 in the same manner as in the first embodiment. Next, the output density and the battery voltage were measured in the same manner as in Example 1. The result is taken as the output density change curve A4, and the battery voltage change is shown as curve B4 as shown in Fig. 6. As shown in Fig. 6, in the comparative example using the container having no vent hole, the battery voltage (curve B 4 ) sharply decreased as the current density increased, and the maximum output density (curve A4) was compared with Examples 1 to 3. reduce. Further, the present invention is not limited to the embodiments described above, and may be modified as long as the constituent elements are changed within the scope of the gist of the invention. Further, various inventions can be formed by appropriately combining a plurality of constituent elements shown in the following embodiments. For example, a plurality of constituent elements may be deleted from all the constituent elements shown in the embodiment. It is also possible to appropriately combine the constituent elements between the different implementation states. -18-200810195 (15) For example, in the above description, the structure of the fuel cell is described as a structure having a fuel storage portion in the lower portion of the membrane electrode assembly (MEA), but the supply of fuel from the fuel storage portion to the membrane electrode assembly is The fuel storage portion and the membrane electrode group may be continuously connected through a flow path. Further, the fuel cell main body is exemplified by a passive type fuel cell. However, a so-called semi-passive type fuel cell in which a pump is used in an active fuel cell or a part of another fuel supply is also applicable to the present invention. In the semi-passive type fuel cell, the fuel supplied from the fuel storage portion to the membrane electrode group is used in the power generation reaction, and is not returned to the fuel storage portion after the cycle. The semi-passive type fuel cell is different from the conventional active type because the fuel does not circulate, so the miniaturization of the non-destructive device is required. In addition, the fuel cell uses a pump to supply fuel, which is different from the conventional internal gasification type of pure passive type. Therefore, it is referred to as a semi-passive type fuel cell as described above. Further, the semi-passive type fuel cell may be configured by replacing the pump with a fuel blocking gate instead of supplying fuel to the membrane electrode assembly from the fuel storage portion. At this time, the fuel blockage is provided by the flow path for controlling the supply of the liquid fuel. As described above, the fuel cell having the same configuration as described above can be obtained. In the steam supplied to the MEA, although all of the fuel may be supplied as steam, the present invention is also applicable to a part of the fuel supplied in a liquid state. [Industrial Applicability] According to the present invention, it is possible to provide a container for accommodating a fuel cell that can control the reduction in output characteristics due to transportation, storage, etc., and to accommodate a fuel cell -19-200810195 (16) A fuel cell with a container.
