This fuel-cell system, in which an anode gas and a cathode gas are supplied and electricity is generated by means of an electrochemical reaction between said gases in accordance with a load, is provided with the following: a compressor that supplies the cathode gas to a fuel-cell stack; and a pressure-regulating valve that regulates the pressure of the cathode gas in said fuel-cell stack. In this fuel-cell system, a target cathode pressure is set on the basis of the electricity-generation demand on the fuel-cell stack, and the operating level of the compressor and the degree to which the pressure-regulating valve is open are controlled on the basis of said target cathode pressure. Also, by constraining the operating level of the compressor and/or the degree to which the pressure-regulating valve is open on the basis of two parameters, namely the temperature at the intake of the compressor and the torque produced by the compressor, the temperature of air discharged by the compressor is constrained to an upper temperature limit. |
