What are the types of fuel cells?

What are the types of fuel cells?

Answer:

Alkaline fuel cell (AFC) - using potassium hydroxide solution as the electrolyte. This electrolyte is highly efficient (up to 60 to 90%) but is sensitive to impurities that affect purity, such as carbon dioxide, and thus require pure hydrogen and oxygen in operation, which limits its use in space flight and International engineering and other fields.

The proton exchange membrane fuel cell (PEMFC) uses an extremely thin plastic film as its electrolyte, which has a high power-to-weight ratio and a low operating temperature, making it ideal for fixed and mobile devices.

Phosphoric acid fuel cell (PAFC) uses phosphoric acid at high temperature of 200 ℃ as its electrolyte, which is suitable for decentralized cogeneration system.

The operating temperature of the molten carbonated fuel cell (MCFC) can reach 650 ° C. This battery is highly efficient, but the material requirements are also high.

Solid Oxygen Fuel Cells (SOFCs) use solid electrolytes (diamond oxides) with good performance, and they require the use of the appropriate materials and process handling technology because the operating temperature of the battery is about 1000 ° C.
