Abstract
In a vehicle having a motor as the drive power source, a fuel cell and battery are on board as the power source for the motor. A target output value for the fuel cell is set within a range such that fuel cell output can track change in power demand. The battery is charged/discharged so as to compensate for delay in fuel cell output relative to power demand. By setting a higher target output value the lower the remaining charge in the battery, the fuel cell can be utilized efficiently while ensuring good output responsiveness.
