Fuel cell is a power generation facility with which chemical energy can be transformed into electric energy directly and efficiently. Fuel cell is less restraint with the efficiency of heat engine and the energy transformation is high and flexible. Fuel cell works no pollution and satisfies the requirement of environmental protection. It is estimated that fuel cell would have extensive prospects and measureless market outlook in power houses, electric vehicles, moving power sources, continuous power sources and space power sources and so on. The domestic and overseas development of fuel cell is introduced in this paper. Their main types (AFC, PAFC, MCFC, SOFC, PEMFC), working principles, advantages, applications and prospects are discussed.
