Abstract
An object of the present invention is to reduce power consumption in a storage apparatus that forms a control purpose power supply while making it possible to detect hydrogen, which has been leaked from a fuel cell system during running, even after stopping the vehicle. To accomplish this object, the power supply for a vehicle controller () is maintained by allowing a self-holding relay () to stay on even after turning off an ignition switch (). On the other hand, the power supply for the vehicle controller () is turned off upon expiry of a predetermined period of time after turning off a propulsion system unless leakage of hydrogen from a fuel cell system () is detected.
