摘要： A fuel cell system includes: a cathode pressure control unit configured to control a pressure of a cathode gas to be supplied to the fuel cell stack on the basis of a load of the fuel cell stack; and an anode pressure control unit configured to control a pressure of an anode gas to be supplied to the fuel cell stack to become higher than the pressure of the cathode gas so that a differential pressure between the pressure of the anode gas and the pressure of the cathode gas becomes a predetermined differential pressure or lower. The anode pressure control unit controls, at a time of recovery from idle stop, the pressure of the anode gas to be supplied to the fuel cell stack to a recovery-time pressure, the recovery-time pressure being obtained by adding the predetermined differential pressure to a predetermined pressure corresponding to an atmosphere pressure.
