FUEL CELL POWER GENERATION SYSTEM AND POLYMER ELECTROLYTE FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide a fuel cell power generation system and a polymer electrolyte fuel cell that implement high power generation efficiency by situationally appropriately humidifying a solid polymer electrolyte membrane into an appropriately wet state.

SOLUTION: The fuel cell power generation system includes: a PEFC 1; a hydrogen gas supply pipe 72 and a hydrogen gas pump 122 for supplying a hydrogen gas to anode side separators; an air supply pipe 73 and an air pump 123 for supplying air to cathode side separators; a humidifying water supply pipe 71 and a humidifying water pump 121 for supplying humidifying water for humidifying fluids to be supplied (hydrogen gas, air); mixing passages of cross passage separators and refining communicating pores of diffusion layers for mixing the fluids to be supplied (hydrogen gas, air) with the humidifying water; a detection sensor 140 for detecting power generation request information to the PEFC 1; and a control unit 130 for controlling the supply amounts of the fluids to be supplied (hydrogen gas, air) and the humidifying water in accordance with the power generation request information.
