Abstract
A control apparatus (6) for a vehicle (V) which includes a fuel cell (11) for generating electricity, auxiliary equipment (12) of the fuel cell (11), a secondary battery (3) to be charged with electricity generated by the fuel cell (11), and a motor (1) to be fed with electricity from the fuel cell (11) and/or the secondary battery (3). The control apparatus (6) commences start-up of the fuel cell (11), supplying electricity from the secondary battery (3) to the auxiliary equipment (12), monitors status of the fuel cell (11), and as the status meets a predetermined condition, computes an electric power at which the secondary battery (3) discharges electricity, based on state of charge of the secondary battery (3) and remaining time to completion of the start-up of the fuel cell (11), and supplies electricity from the secondary battery (3) to the motor (1) at the computed electric power.
