Description

Fuel cell manufacturing system

The present invention relates to a fuel cell manufacturing system, and more specifically, to prevent damage to the cathode layer and the anode layer during the cementation process between the anode layer, the electrolyte layer, and the anode layer. It relates to a fuel cell manufacturing system that can prevent and reduce the positional difference between the cathode layer and the anode layer during the cementation process.

A chemical cell is a device that converts the energy change when a chemical change occurs into electrical energy. Generally, in a chemical cell, the materials that make up the electrode and the electrolyte are placed in a container and undergo a chemical reaction.

However, a fuel cell continuously supplies hydrogen and oxygen from the outside to continuously produce electrical energy. This is similar to supplying a mixture of fuel and air into an engine for combustion.

A chemical cell that resembles the combustion of fuel is called a fuel cell. In other words, a fuel cell refers to a device that directly converts the chemical reaction energy of hydrogen contained in hydrocarbon-based materials such as methanol, ethanol, and natural gas and oxygen supplied from outside into electrical energy.

As shown in Figure 1, the fuel cell is a cell (see (a) in Figure 1) with a structure in which a cathode layer, an electrolyte layer, an anode layer, and a separator layer are stacked. With is as the basic unit, a structure is formed by stacking a plurality of cells as shown in (b) of FIG. 1 to obtain the required amount of current.

The cathode layer, electrolyte layer, and anode layer must be bonded on the surface between each layer, but the cathode layer, electrolyte layer, and anode layer are easily broken due to their material characteristics, that is, due to their thickness and material characteristics.

Therefore, a sub gasket (10) made of polymer film as shown in FIGS. 2 and 3 is used. That is, a state or structure (this is called an assembly 20) in which the cathode layer, electrolyte layer, and anode layer are bonded is created in the hole 11 area of the sub gasket 10, and this assembly 20 is formed. During handling, a separator and stack structure are created.

The sub gasket 10 has a structure with a hole 11 in the center of the film as shown in FIG. 4. In other words, the sub gasket 10 is provided in a frame-like structure with the film on the edge.

After parts of the cathode layer, electrolyte layer, and anode layer are placed on the edge film portion of the sub gasket 10 based on the hole 11, the cathode layer and electrolyte layer are placed on the hole 11 of the sub gasket 10. and the anode layer is bonded. For reference, the electrolyte layer may be already bonded to the cathode layer or the anode layer, then handled as one body and placed on the sub gasket 10.

Meanwhile, when making the assembly 20, which is a single body structure, by placing and bonding the cathode layer, electrolyte layer, and anode layer in the hole 11 area of the sub gasket 10, a hot-press roller was conventionally used. ) method was applied. That is, after applying adhesive in advance to one side of the cathode layer, electrolyte layer, and anode layer, they are bonded into one body while passing through a hot press roller.

Although this method is commonly used, several problems arise in this conventional method as shown below.

First, during the operation of the hot press roller, the cathode layer, electrolyte layer, and anode layer may be damaged by the roller. That is, the cathode layer is weakly attached to the sub gasket 10 by the cathode layer transfer device, and the anode layer is weakly attached to the sub gasket 10 by the anode layer transfer device, so the corners of the cathode layer or anode layer may be lifted. It may be damaged when it comes in contact with a hot press roller.

Second, the cathode layer and the anode layer must be placed in precise positions according to their relative positions and then bonded to that position, but as the process is repeated, the positional deviation between bonding processes may increase. In reality, the cathode layer or anode layer transfer device can move according to the set value, but since the cathode layer and anode layer input into the transfer device may be input with a large positional deviation, the positional deviation between the cementing processes can increase, leading to an increase in the defect rate. It will happen.

Hereinafter, the present invention will be described in detail by explaining preferred embodiments of the present invention with reference to the accompanying drawings. The same reference numerals in each drawing indicate the same member.

Referring to these drawings, the fuel cell manufacturing system according to this embodiment prevents the cathode layer and anode layer from being damaged during the cementation process between the anode layer, electrolyte layer, and cathode layer. Meanwhile, it reduces the positional difference between the cathode layer and the anode layer during the cementation process.

The fuel cell manufacturing system according to this embodiment that can provide such effects includes a sub-gasket supply device 500, a gasket hole forming device 100, a PRE Tack device 200, a lamination device 300, and It may include an assembly separation device 500. These devices are sequentially placed on the line supplied to the process as the sub gasket (10) is released, that is, inline, and proceed with a continuous process, so that the above-described assembly (20) can be formed. do.

As briefly mentioned earlier, the cathode layer, electrolyte layer, and anode layer must be bonded on the surface between each layer, but the cathode layer, electrolyte layer, and anode layer are fragile due to their material characteristics, that is, due to their thickness and material characteristics. , taking this into consideration, a sub gasket (10) made of polymer film is used. At this time, the state or structure in which the cathode layer, electrolyte layer, and anode layer are bonded to the hole 11 area of the sub gasket 10 is called an assembly 20.

As shown in FIG. 6, the sub gasket supply device 500 processes the sub gasket 10 to manufacture the assembly 20, which is formed as one body by bonding the cathode layer, the electrolyte layer, and the anode layer. It plays a role in supplying.

This sub gasket supply device 500 includes an unwinder 510 that unwinds and supplies the web-shaped sub gasket 10 to the process, and a sub gasket disposed on the process line and unwinded from the unwinder 510. It includes a plurality of guide rollers 520 that guide (10).

Of course, in addition to the guide roller 520, there is a drive roller (not shown) that holds and pulls the sub gasket 10, a meander stopper (not shown) that prevents the meandering of the sub gasket 10, and a loosening amount of the sub gasket 10. The sub gasket supply device 500 may be further equipped with a sensor (not shown) to detect the gasket, but details about this will be omitted.

Referring to FIGS. 5 to 7, the gasket hole forming device 100 is disposed between the sub gasket supply device 500 and the pre-tack device 200, and forms a hole 11 on the sub gasket 10. It plays a role. The gasket hole forming device 100 may be a type of punch structure. The cathode layer, electrolyte layer, and anode layer can be bonded through the hole 11 formed on the sub gasket 10 to form one assembly 20.

Before explaining the pre-tack device 200 and the lamination device 300, let's first look at the assembly separation device 500. The assembly separation device 500 is a device of the lamination device 300 as shown in FIGS. 5 and 6. It is placed at the rear of the process and serves to separate the assembly 20 formed after lamination has been completed.

In this embodiment, the assembly separation device 400 is applied as a gasket cutter 400 to cut the continuous sub gasket 10 into unit sizes. By the gasket cutter 400, continuous sub gaskets 10 on a web can be cut into unit sizes together with one assembly 20.

Of course, it is possible to remove only the assembly 20 from the sub gasket 10 without using the gasket cutter 400, that is, without cutting the entire continuous sub gasket 10 on the web. This structure Again, it may be included in the assembly separation device 400.

Meanwhile, as shown in FIGS. 5 and 6, the pre-tack device 200 is disposed on one side of the process line where the sub gasket 10 is supplied, that is, disposed behind the process of the gasket hole forming device 100 in the in-line process. It serves to align each of the cathode and anode layers, place them on the sub gasket 10, and pre-bond them. At this time, the electrolyte layer is considered to have been previously bonded to one of the cathode layer and the anode layer.

And, as shown in FIGS. 5 and 6, the lamination device 300 is disposed behind the process of the pre-tack device 200 in the in-line process, and laminations the cathode layer and the anode layer with the electrolyte layer interposed therebetween. ) plays a role.

In this embodiment, the lamination device 300 is a flat type flat-to-flat lamination device 300 that laminates the cathode layer and the anode layer while pressing them. The assembly 20 is finally completed by passing through the flat-to-flat lamination device 300.

In this way, unlike the prior art, the fuel cell manufacturing system according to this embodiment uses the pre-tack device 200 and the lamination device 300. Due to the application of these devices 200 and 300, the fuel cell manufacturing system according to this embodiment is used during the cementation process between the cathode layer, electrolyte layer, and anode layer. It prevents the cathode and anode layers from being damaged and reduces the positional difference between the cathode and anode layers during the cementation process.

First, let's take a closer look at the free tack device 200. 5 to 15, the pre-tack device 200 is disposed behind the process of the gasket hole forming device 100 in the in-line process, and aligns each of the cathode layer and the anode layer to form the sub gasket 10. It plays a role in oligomerization and cementation.

The pre-tack device 200 is arranged in a pair on both sides with the sub gasket 10 in between. In that one of the pair of pre-tack devices 200 pre-tacks the negative plate and the other pre-tacks the positive plate, only the object is different, but the structure and function are all the same. Therefore, the same reference numerals were assigned.

The pre-tack device 200 includes a magazine unit (210, Magazine Unit) in which the cathode layer or anode layer is laminated and stored, an alignment unit (220, Align Unit) that aligns the cathode layer or anode layer, and an alignment unit. It may include a turn turret unit (230) that transfers the cathode layer or anode layer aligned by 220 to the sub gasket 10 and pre-tacks it.

Additionally, in this embodiment, the pre-tack device 200 is disposed between the magazine unit 210 and the alignment unit 220, and transfers the cathode layer or anode layer on the magazine unit 210 to the alignment unit 220. It is disposed between the first transfer unit 201 (Transfer Unit), the alignment unit 220, and the turn turret unit 230, and turns the cathode layer or anode layer on the align unit 220 into the turn turret unit 230. It further includes a second transfer unit (202, Transfer Unit) that transfers to.

The first transfer unit 201 is a unit that pulls the cathode layer or anode layer using a vacuum chuck, etc. to separate it from the magazine unit 210, and aligns the cathode layer or anode layer by moving upward and to the left. It is placed on the align stage 221 of (220), and the cathode layer or anode layer can be loaded on the align stage 221 through an unchucking process. The second transfer unit 202 also operates in the same manner as the first transfer unit 201.

Looking at the configurations in more detail, the magazine unit 210 forms a place where the cathode layer or the anode layer is stacked and stored. Ultimately, in the case of this embodiment, a single sheet of cathode or anode layer is applied, but unlike the drawing, the cathode or anode layer may be provided in the form of a web rather than a sheet and then cut.

The alignment unit 220 is a means for aligning the cathode layer or anode layer transferred from the magazine unit 210 through the first transfer unit 201.

This alignment unit 220 controls the alignment stage 221 (Align Stage) on which the cathode layer or anode layer is loaded and aligned, and the alignment position of the cathode layer or anode layer loaded on the align stage 221. Includes a camera that takes pictures (222, Camera).

The alignment stage 221 includes a device capable of alignment in plane coordinates. Accordingly, when the first transfer unit 201 loads the cathode layer or the anode layer from the magazine unit 210 onto the align stage 221, the camera 222 photographs the alignment mark, and based on this information, the align stage By driving 221, the correct position of the cathode layer or the anode layer is determined. Then, since the second transfer unit 202 simply picks up the aligned cathode layer or anode layer and transfers it to the turn turret unit 230, the process is convenient and there is no concern about misalignment.

The turn turret unit 230 transfers the cathode layer or anode layer transferred from the alignment unit 220 through the second transfer unit 202 to the sub gasket 10 and serves to pre-tack.

The turn turret unit 230 includes a unit body 240, a heating loading part 250 that forms a place where the cathode layer or anode layer is loaded and heated while being pressed toward the sub gasket 10, the unit body 240, and a heating unit 230. It is connected to the loading unit 250 and may include a loading pressing unit 260 that pressurizes the heating loading unit 250.

This turn turret unit 230 is a type of transfer unit, and serves to transfer the cathode layer or anode layer, for example, the cathode layer placed on the heating loading unit 250, to the sub gasket 10 and pre-tick it. . That is, when the cathode layer is placed on the heating loading part 250, the cathode layer is chucking using the vacuum hole (252, vacuum hole, or vacuum chuck) in the stage plate 251 of the heating loading part 250. Afterwards, turn (Trun) 180 degrees so that the cathode layer faces the sub gasket (10). The heating loading part 250 allows the cathode layer and the sub gasket 10 to adhere to each other through the action of the loading pressurizing part 260. At this time, as the first heating element 253, for example, a sheath type heater, is built into the heating loading unit 250, heat is transferred to the cathode layer and the sub gasket 10, and this pressing force It causes pre-tack by overheating.

In this embodiment, a pair of heating loading units 250 are provided symmetrically on both sides of the unit body 240. Accordingly, while the cathode layer or anode layer is transferred to the sub gasket 10 from one heating loading unit 250 and pre-tapped, the cathode layer or anode layer to be worked on can be newly transferred to the other heating loading unit 250. . Therefore, productivity can be increased by reducing the tact time.

Looking at the heating loading unit 250 in more detail, the heating loading unit 250 includes a stage plate 251 on which a cathode layer or an anode layer is loaded and a plurality of vacuum holes 252 are formed, and a stage A first heating element 253 is provided in the plate 251 and heats the stage plate 251, and a first insulating plate 254 connected to the loading pressurization unit 260 and providing an insulating function. , It may include a first connection plate 255 connecting the stage plate 251 and the first insulation plate 254.

Since the vacuum hole 252 is formed in the stage plate 251, the cathode layer or the anode layer can be loaded on the loading surface of the stage plate 251 without shaking.

The loading pressurizing unit 260 is connected to a cylinder 261 provided in the unit body 240, a loading support unit 262 supporting the heating loading unit 250, and the cylinder 261 and the loading support unit 262. , It may include a pressing shaft 263 that pressurizes the loading supporter 262 by the action of the cylinder 261.

For reference, in FIGS. 8 to 12, the pre-tack device 200 is shown as moving the cathode layer or the anode layer sequentially, but operations for each unit may be performed simultaneously. In this case, the takt time can be further shortened, contributing to improved productivity.

Next, the flat-to-flat lamination device 300 is a flat type, as described above, and serves to laminate the cathode layer and the anode layer by pressing them. The assembly 20 is finally completed by passing through the flat-to-flat lamination device 300.

This flat-to-flat lamination device 300 applies heat and pressure to the outer surfaces of each of the cathode and anode layers attached on the sub gasket 10 through the free tack device 200 to attach the inner surfaces of each of the cathode and anode layers, That is, the edge side of the inner surface of the cathode layer and the upper surface of the sub gasket (10) are attached, while the edge side and the lower surface of the sub gasket (10) are attached to the inner surface of the anode layer. Of course, the arrangement positions of the cathode layer and the anode layer based on the sub gasket 10 may be opposite to those shown in the drawing.

Since the flat-to-flat lamination device 300 applied in this embodiment is a hot press plate type rather than the conventional roller type, damage to the cathode layer and anode layer during the cementation process is possible. Not only can it prevent this, but it can also reduce the positional difference between the cathode layer and the anode layer during the cementation process.

These flat-to-flat lamination devices 300 may be arranged as a pair on both sides with the sub gasket 10 in between, as shown in FIGS. 5 and 6 and FIGS. 16 to 21. A pair of flat-to-flat lamination devices 300 have the same structure, function, and role, except that the working objects are a cathode layer and an anode layer.

This flat-to-flat lamination device 300 includes a heating plate 310 that pressurizes the cathode layer or the anode layer with heat, a second heating element 320 provided in the heating plate 310, and a second heating element 320 that heats the heating plate 310. a heating element), a second insulation plate 330 that provides an insulation function, a second connection plate 340 connecting the heating plate 310 and the second insulation plate 330, and a second insulation plate 330 ) and may include a plate pressing unit 350 that pressurizes the heating plate 310. The plate pressing unit 350 may be applied as a cylinder or the like.

Accordingly, in a state where the cathode layer and the anode layer are pre-tacked by the action of the pre-tack device 200 as shown in FIG. 17, they are laminated through the flat-to-flat lamination device 300 as shown in FIGS. 18 to 20 to form the assembly 20 as shown in FIG. 21. It can be made, and then the separation process can be performed through the assembly separation device 400.

According to this embodiment, which operates with the structure described above, the cathode layer and the anode layer are prevented from being damaged during the bonding process between the cathode layer, the electrolyte layer, and the anode layer, and the positional deviation of the cathode layer and the anode layer between the bonding processes is prevented. can be reduced.

Figure 22 is a modified embodiment of a turn turret unit.

Referring to this drawing, the turn turret unit 230a applied to this embodiment also has a heating loading unit that forms a place where the unit body 240 and the cathode layer or anode layer are loaded and heated while being pressed toward the sub gasket 10. It is connected to the unit 250, the unit body 240, and the heating loading unit 250, and may include a loading pressurizing unit 260 that pressurizes the heating loading unit 250. Their structure, function, and role are the same as the above-described embodiment. Therefore, avoid duplicate explanations.

Meanwhile, in this embodiment, a plurality of protrusions 251a are further formed on the loading surface of the heating loading part 250 where the cathode layer or the anode layer is loaded.

The protrusion 251a is a structure that efficiently increases the pressure transmitted to the cathode layer or the anode layer. Since pressure is inversely proportional to the contact area, the structure of the protrusion 251a is designed to increase the local pressure by reducing the contact area. The pressure can be increased locally, but the important part, that is, the border part, can be bonded.

Figure 23 is a modified example of a flat-to-flat lamination device.

Their structure, function, and role are the same as the above-described embodiment. Therefore, avoid duplicate explanations.

Meanwhile, in this embodiment, a cushion layer 360 is provided on the exposed surface of the heating plate 310. The cushion layer 360 on the upper surface of the heating plate 310 is a means to apply even pressure to the cathode layer or the anode layer.
