An ECU of a control apparatus further alleviates a fluctuation in a power generation amount of a fuel cell stack with respect to the power required by an inverter apparatus, when a power supply circuit configured by each of contactors and a power supply inlet 11a supplies the power to the inverter apparatus compared with when a vehicle is driving. The ECU, when the power supply circuit supplies power to the inverter apparatus, stops the power generation of the fuel cell stack in a case where a remaining capacity in a battery is greater than or equal to a predetermined remaining capacity, and inhibits the fuel cell stack from stopping the power generation in a case where the power supplied to the inverter apparatus by the power supply circuit is greater than or equal to a predetermined power supply amount.
