To perform proper uses of the outputs of the respective energy outputting sources of a vehicle, having a plurality of energy outputting sources including a fuel cell for its auxiliary machinery.

In a vehicle, an engine 10, a fuel cell 60, and a battery 50 are mounted as its energy outputting sources. Its auxiliary machinery is made drivable by the power outputted from the engine 10. Furthermore, its auxiliary machinery is also made drivable by driving a motor 80 through the use of the fuel cell 60 and the battery 50. In such a configuration, its auxiliary machinary is driven in the order of priorities as the engine 10, a fuel cell 60, and the battery 50 when its ignition switch is turned on. In the other cases, its auxiliary machinery is driven in the order of priorities as the fuel cell 60 and battery 50. Thereby, its driving efficiency and its environmental quality can be improved.
