Solar photovoltaic power generation and a fuel cell are combined and comprehensively applied to the electric automobile. A solar photovoltaic power generation system directly supplies power to a power battery, an automotive load and a water electrolysis container. The water electrolysis container is used for preparing hydrogen so that a hydrogen energy source can be supplied to a fuel cell power generation system. The power battery is boosted through a bidirectional DC/DC transducer and then transmits high-voltage direct-current electric energy to the input end of the bidirectional transducer. The output end of the bidirectional transducer is directly connected with a drive motor. The electric energy generated by the fuel cell power generation system is boosted through a unidirectional DC/DC transducer and then is connected to the input end of the bidirectional transducer in parallel, and generated water is conveyed to the water electrolysis container at the same time. When the electric energy of the power battery is low, the fuel cell power generation system can charge the power battery, and therefore the electricity demand of the automotive load and the traveling requirement are met.
