Fuel cell system using hydrogen from electrolyzer of sea water

The present invention relates to a fuel cell system using waste hydrogen generated from a seawater electrolysis facility, and more particularly, in a seawater electrolytic facility which generates chlorine material by electrolyzing seawater used as cooling water in a nuclear power plant and a thermal power plant. The present invention relates to a fuel cell system that generates electricity by using waste hydrogen generated as a fuel.

In general, a nuclear power generation and thermal power generation system 1, as shown in Fig. 1, a reactor 2 in which a nuclear reaction takes place, heat exchange means 3 for cooling and heat exchange of the reactor, steam generated from the heat exchange means It comprises a generator 7 for generating power by using and a cooling means (8) for cooling the steam. In addition, it is configured to further include a steam generator (4) for steam generation.

In nuclear power and thermal power generation systems, cooling water for cooling high-temperature water passing through a turbine or cooling a heat exchanger is introduced from the sea, and waste cooling water is discharged from the volleyball water to the sea. Normally, the cooling water at room temperature flowing into the nuclear power and thermal power generation system is heated up to about 90 ° C through heat exchange for cooling, and the waste coolant is separated separately through the cooling system so that it is not higher than a certain temperature (about 7 ° C) or higher than the surrounding seawater. It is cooled and discharged.

Thus, in order to secure a large amount of cooling water used in nuclear power and thermal power generation systems, seawater is generally used as a cooling water.In the cooling water intake facility connected to the seawater channel, the adhesiveness of fish and shellfish such as mussels and shellfish and seaweed is usually used. Life is growing, and these marine organisms enter the cooling water intake plant through seawater channels that provide ideal environmental conditions with warm temperatures and slow flow rates. As such, marine organisms flowing into the cooling water intake facility are usually attached to and grown on the inner wall of the seawater channel or the respective components of the cooling water intake facility including the same, causing corrosion and damage to these components. Depending on the size, the seawater channel or the cooling water intake facility is partially or totally closed, which reduces the efficiency of the cooling water pump and damages or decreases the inflow of seawater, as well as the corrosion of the related equipment such as condensers and heat exchangers, and its operation. Is causing problems.

In order to solve this problem, the seawater electrolysis facility 10 is installed in the nuclear power generation and thermal power generation systems as shown in FIG.

Reacts to produce chlorine. That is, among the ions (Na, Cl, H, OH) generated by the electrolysis of NaCl and H ₂ O in seawater by the DC current supplied through the rectifier, Cl moves to the anode to form chlorine (Cl ₂ ), and H Moves to the cathode to generate hydrogen gas (H ₂ ). Na, which is more reactive than Cl, exists in an ionic state. NaOH is produced by combining with OH, and the produced sodium hydroxide (NaOH) reacts with chlorine (Cl ₂ ) to produce chlorine (NaOCl). Since the amount of electrolysis varies depending on the size of the sodium hypochlorite concentration can be adjusted.

Chlorine material generated in the seawater electrolysis facility and hydrogen generated by the secondary are moved to the storage tank 13 through the check valve, the hydrogen gas of the upper double storage tank is discharged to the atmosphere through the blower (14). In other words, current seawater electrolytic facilities are just flowing to the atmosphere without any waste hydrogen generated by the incident.
