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 first detection line is set in a lower temperature range than a limit line representing an upper limit temperature of a motor allowed by an inverter and represents a reference motor temperature at a required output for fuel cells as a temperature criterion where a controller changes over the means for achieving the sufficient hydrogen stoichiometric ratio from recycling hydrogen with a circulation pump to increasing the hydrogen concentration. When the motor temperature reaches or exceeds the first detection line at the required output for the fuel cells, the controller prevents an increase in rotation speed of the motor and regulates the openings of a shutoff valve and a regulator to increase the concentration of hydrogen supplied from a hydrogen tank to the fuel cells and thereby increase the hydrogen supply pressure. This arrangement effectively prevents an increase of the motor temperature, while achieving the sufficient hydrogen stoichiometric ratio.
