What types of fuel power batteries are there?

Currently, there are 5 known fuel power cell types. Its name is related to the corresponding electrolyte used. (1) Alkaline fuel power cell (AFC) uses potassium hydroxide solution as electrolyte. This electrolyte is very efficient (up to 60-90%), but it is very sensitive to impurities that affect purity, such as carbon dioxide. Therefore, pure hydrogen and oxygen must be used in operation. This restricts its application in fields such as space flight and international engineering. (2) Proton exchange membrane fuel power cell (PEMFC) uses extremely thin plastic film as its electrolyte. This electrolyte has a high power-to-weight ratio and low operating temperature. It is an ideal material for fixed and mobile devices. (3) Phosphoric acid fuel cell (PAFC) uses phosphoric acid at a high temperature of 200°C as its electrolyte. It is very suitable for decentralized cogeneration systems. (4) The operating temperature of Molten Carbonated Fuel Power Cell (MCFC) can reach 650℃. The efficiency of this battery is very high, but the requirements for material requirements are also high. (5) Solid-state electrolyte (diamond oxide) is used in solid-state oxygen fuel cell (SOFC), which has good performance. They have to adopt the corresponding materials and process technology, because the operating temperature of the battery is about 1000 ℃.
