What are the types of hydrogen power generation?

Phosphate fuel cell
Phosphate fuel cells are the earliest type of fuel cells, and the process is basically mature. The United States and Japan have built commercial power stations of 4,500 kilowatts and 11,000 kilowatts respectively. The operating temperature of this fuel cell is 200°C, the maximum current density can reach 150 mA/cm2, and the power generation efficiency is about 45%. The fuel is hydrogen, methanol, etc., the oxidant is air, but the catalyst is platinum series. Currently, it generates electricity The cost is still high, about 40 to 50 cents per kilowatt hour.
molten carbonate fuel cell
Molten carbonate fuel cells are generally called second-generation fuel cells. Their operating temperature is about 650°C and their power generation efficiency is about 55%. Mitsubishi Corporation of Japan has built a 10-kilowatt power generation device. The electrolyte of this type of fuel cell is liquid. Due to its high operating temperature, it can withstand the presence of carbon monoxide. The fuel can be hydrogen, carbon monoxide, natural gas, etc. The oxidizing agent is air. The cost of generating electricity can be less than 40 cents per kilowatt hour.
solid oxide fuel cell
Solid oxide fuel cells are considered to be the third generation of fuel cells. Their operating temperature is about 1000°C and the power generation efficiency can exceed 60%. Many countries are currently studying it. It is suitable for building large power stations. Westinghouse Company of the United States is developing it. , the cost of generating electricity is expected to be less than 20 cents per kilowatt hour.
