    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.

    摘要： In order to make a power generation quantity of a cell for fuel cell increase in a short time when a drop in moistness of the cell causes the power generation quantity of the cell to decrease, a cathode of the cell includes a conductive material, catalyst, and ionomer which covers the conductive material and catalyst. If an output voltage value VFC of the cell is lower than a predetermined threshold voltage value VFCTH and an electrical resistance value RFC of the cell is higher than a predetermined threshold resistance value RFCTH, control for increasing an oxidizing gas amount which increases an amount QOFC of oxidizing gas sent to the cell is performed.

    摘要： An object is to suppress drying of a fuel cell during continuous operation with high load. There is provided a fuel cell system including a fuel cell. The fuel cell system comprises an impedance detector that is configured to detect an impedance of the fuel cell; and a current limiter that is configured to limit an output current of the fuel cell with a limiting rate. The current limiter changes the limiting rate, based on the detected impedance.
