A fuel cell system that generates power by supplying anode and cathode gases to a fuel cell, comprising a compressor configured to adjust a flow rate of the cathode gas supplied to the fuel cell, a relief valve configured to adjust a pressure of the cathode gas supplied to the fuel cell, a pulsation operation unit configured to pulsate an anode gas pressure, a target flow rate setting unit configured to set a target flow rate of the cathode gas on the basis of a request from the fuel cell, a first target pressure setting unit configured to set a first target pressure of the cathode gas on the basis of a request from the fuel cell, a second target pressure setting unit configured to set a second target pressure of the cathode gas for maintaining a pressure difference between an anode and a cathode of the fuel cell within a predetermined allowable pressure difference range, a target pressure setting unit configured to set the higher one of the first and second target pressures as a target pressure, and a control unit configured to control the compressor and the relief valve on the basis of the target flow rate and the target pressure. The control unit controls the compressor on the basis of the target flow rate and a limitative pressure obtained by limiting pulsation of the target pressure when the target pressure is pulsated in response to pressure pulsation of the anode gas. |
