ABSTRACT:
An electric vehicle10includes a power supply apparatus15. The power supply apparatus15includes a fuel cell system22, capacitor24and secondary battery26that are connected in parallel to wiring50. When a drive motor is performing regeneration, the capacitor24is collecting the regenerated electric power. The fuel cell system22generates electric power in accordance with the load demand. The switches20between the fuel cell and the wiring are closed when the load becomes small and the regenerated voltage attains a predetermined level. As a result, the generation of electric power by the fuel cell system is suspended under low-load conditions where the energy efficiency of the fuel cell system22is low.
