Fuel cell (Fuel Cell) is a power generation device that directly converts chemical energy that exists in fuel and oxidant. Its single battery is two electrodes of positive and negative (negative electrode, which is fuel electrodes and positive electrodes of oxidant electrodes) and the electrode Electrolyte composition, the difference is that the active substances of general batteries are stored inside the battery, which limits the battery capacity. The positive and negative electrodes of the fuel cell do not include active substances, but it is just a catalytic conversion element. Therefore, the fuel cell is a energy conversion machine that converts chemical energy into electrical energy. When the battery works, fuel and oxidant are supplied by the outside for reaction. In principle, as long as the reaction is continuously entered and the reaction product is constantly excluded, the fuel cell can be continuously generated. Here is a hydrogen-oxygen fuel cell as an example to illustrate the fuel cell

　　The principle of hydrogen-oxygen fuel cell reaction is the inverse process of electrolytic water.

　　The electrode should be: negative electrode: H2 +2OH- → 2H2O +2E-;

　　Corporation: 1/2O2+H2O+2E- → 2OH-;

　　Battery response: H2+1/2O2 == H2O.

　　Fuel battery component part

　　1. Electrode

　　The electrode of the fuel cell is an electrochemical response place where the fuel oxidation reaction and the oxidant reaction reaction occurs.

　　The electrode is divided into two parts, one is anode, and the other is cathode.

　　2. Electrolyte Membrane

　　The main function of the electrolyte diaphragm lies in separate oxidants and reducing agents, and transmit ions;

　　3. Current collectionor

　　Electrical appliances, also known as bipolar play, have the functions of collecting current, dividing oxidant and reducing agent, dredging reaction gas, etc.

　　4. Auxiliary system

　　Reactive supply system, heat drainage system, drainage system, electrical control control system, safety device, etc.

　　Fuel batteries are usually composed of electrolyte boards that form ionic electricals and their fuel poles (anodes) configured on both sides and air (cathode), and gas flow on both sides. Gas) can be passed in the flow road.

　　According to different fuel treatment, it can be divided into direct, indirect and regeneration. Direct fuel cells can be divided into three types: low temperature, medium temperature and high temperature. The indirect type includes reorganization fuel cells and biofuel batteries. There are light, electricity, heat, radiochemical fuel cells, etc. in regenerative fuel batteries. According to different electrolyte types, it can be divided into alkaline, phosphate, polymerization, melting carbonate type, solid electrolyte fuel cells.
