FUEL-CELL SYSTEM AND METHOD FOR CONTROLLING FUEL-CELL SYSTEM

A fuel cell system includes: a compressor configured to adjust a flow rate of a cathode gas to be supplied to a fuel cell; a pressure regulating valve configured to adjust a pressure of the cathode gas to be supplied to the fuel cell; a target pressure calculating unit configured to calculate a target pressure of the cathode gas to be supplied to the fuel cell while taking into consideration a load of the fuel cell and a heat protecting requirement of the fuel cell system; a target pressure calculating unit configured to calculate a target pressure of the cathode gas to be supplied to the fuel cell while taking into consideration a load of the fuel cell and a heat protecting requirement of the fuel cell system; a target flow rate calculating unit configured to calculate a target flow rate of the cathode gas to be supplied to the fuel cell in accordance with the load of the fuel cell and the target pressure of the cathode gas; and a control unit configured to control the compressor and the pressure regulating valve in accordance with the target pressure and the target flow rate of the cathode gas.
