  • Patent number: 11063277
    Abstract: A method of controlling ignition of a vehicle having a fuel cell system is provided. In particular, the method includes a step of determining an idling state of the vehicle, a step of determining whether to enable a fuel cell on/off mode, a step of determining a degree of water balance of a fuel cell stack, and a step of turning off a vehicle's ignition switch. More specifically, a fuel cell system controller determines whether to enable a fuel-cell on/off mode based on a coolant temperature of the fuel cell system once the idling state is determined, and also determines a degree of water balance of a fuel cell stack of the fuel cell system. The fuel cell system controller turns off the vehicle's ignition switch, when a predetermined time passes, based on the degree of water balance.
