Outward power supply control fuel cell vehicle


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..

Moving body


A fuel cell vehicle is provided that allows for filling as much fuel gas as possible. The vehicle includes a high-pressure tank, a communication system, a communicative filling ecu that selectively executes communicative filling that transmits a data signal from the communication system to the dispenser and allows hydrogen to be filled by way of the dispenser into the tank at a flowrate dependent on the pressure and the temperature; and non-communicative filling that does not transmit a data signal from the communication system and allows hydrogen to be filled at a predetermined flowrate.
