Abstract
To restrain deterioration of fuel cells while preventing a battery from being overcharged, a fuel cell vehicle includes a motor for providing torque to wheels, a battery for storing electric power to provide the stored electric power to the motor, and a FC stack for generating electric power to provide the generated electric power to the motor and the battery. A battery charge level determining module determines a battery charge level of the battery, and a FET is configured to connect or disconnect the FC stack to the motor and the battery. A controller is configured to cause the FET to disconnect the FC stack from the motor and the battery and allow power generation by the FC stack when the determined battery charge level by the battery charge level determining module is greater than or equal to a first predetermined threshold.
