    摘要： Deterioration of an electrolyte and a sealing member is suppressed taking account of the durable temperature characteristics thereof, while enhancing the starting performance of a fuel cell. For this realization, in a system comprising a gas piping system for supplying a reactant gas to a fuel cell, and a gas supply controller for altering the supply state of the reactant gas in response to a power generation request, a gas supply quantity is altered in accordance with the temperature of the fuel cell. Preferably, the gas supply quantity is altered in accordance with the durable temperature characteristics of a passage member forming a gas passage of the reactant gas. Furthermore, the differential pressure of the gas supply state between the anode side and the cathode side of the fuel cell is preferably taken into account and the differential pressure between both poles is suppressed by altering the gas supply quantity on the cathode side as the case may be.

    摘要： A fuel cell system having a fuel cell, a fuel supply flow path for allowing a fuel gas supplied from a fuel supply source to flow to the fuel cell, an on-off valve for regulating the state of the gas on the upstream side of the fuel supply flow path to supply it to the downstream side, failure detection means for detecting whether the on-off valve has a closure failure, a pressure sensor for detecting the pressure value of the fuel gas on the upstream side of the on-off valve, and determination condition setting means for setting, based on the pressure value detected by the pressure sensor, the conditions of determination of the closure failure of the on-off valve. The failure detection means determines whether the on-off valve has the closure failure, based on the closure failure determination conditions set by the determination condition setting means.
