  • Patent number: 10118491
    Abstract: A control method for a fuel cell vehicle includes a failure determining step of determining whether or not a failure exists in a fuel cell system. A safe driving step stops an operation of the fuel cell system and drives the vehicle using only a high voltage battery system when the failure exists in the fuel cell system. A temporary stopping step determines a driving state of the vehicle and temporarily stops an operation of the high voltage battery system when it is determined that the driving state is a stop state. A re-driving step re-operates the high voltage battery system to restart the vehicle when the driving state is converted into a start state.
