ABSTRACT:
When a request to stop an operation of a fuel cell system is issued, a control unit stops the operation of the fuel cell system and cuts off the electrical connection between the fuel cell and a drive motor by shutting OFF a power supply relay. Where a shift position signal indicating that the shift position SP is at the P or N position is received from a shift selector and the parking brake is set, the control unit determines whether a coolant temperature Tfc detected via coolant detection sensors is at or below 20° C. If it is determined that the detected coolant temperature Tfc is at or below 20° C., the control unit commences a temperature-maintenance operation process.
