摘要： In a case where gas supply controller of an FC system determines that the temperature of an FC is a predetermined temperature or less, the gas supply controller fixes the FC voltage to a voltage value within a voltage region where degradation is relatively small, the voltage value being below a voltage range where an oxidation-reduction proceeds. Further, the amount of a gas supplied to the FC is changed in accordance with electric power required by a load.

摘要： Provided is a fuel cell system for having a fuel cell generate electric power corresponding to a requirement by a power consuming load, with improving the durability of the fuel cell. The fuel cell system comprises: a fuel cell stack, an air pump, a first convertor, a motor, an ECU controlling the air pump and the first convertor based on the target voltage and switching voltage of the single cell. The ECU executes the first mode such that the actual voltage of the single cell corresponds to the target voltage, when the target voltage is not more than the switching voltage, while the ECU executes the second mode such that the actual voltage of the single cell is kept at the switching voltage, when the target voltage is more than the switching voltage. The second mode is executed by changing the actual current of the single cell.
