Here, the water electrolysis device is provided with a first gas path and a second gas path; the first gas path is connected with the hydrogen storage unit, and the second gas path is connected with the fuel cell component. One end of the hydrogen storage unit is connected with the first gas path, and part of hydrogen generated by the water electrolysis equipment is stored in the hydrogen storage unit through the first gas path; the other end of the hydrogen storage unit is connected with the fuel cell component and used for conveying hydrogen to the fuel cell component.

In addition, the water container is connected with the water electrolysis equipment and is used for conveying water to the water electrolysis equipment; the fuel cell component is also provided with a water circulation channel which is connected with the water container, and water generated by hydrogen consumed by the fuel cell component through reaction is conveyed into the water container through the water circulation channel; in addition, the fuel cell assembly is also provided with a circuit which is connected with the water electrolysis device, so that the electric energy generated by the fuel cell assembly is transmitted to the water electrolysis hydrogen production device. For example, when the fuel cell assembly does not supply power to the outside or has residual capacity after supplying power to the outside, the residual capacity can be supplied to the water electrolysis equipment, so that the supply of external energy is reduced, and the energy utilization rate is improved.

The novel fuel cell system in the embodiment realizes online power generation by using the connection of the light energy conversion unit, the water electrolysis equipment and the fuel cell assembly. The combination of the hydrogen storage unit and the water electrolysis equipment is utilized to store electric energy. The way of storing electric energy in the existing battery is changed. The light energy conversion unit may be a solar energy conversion unit. For example, in the daytime, the solar energy conversion unit converts solar energy to provide electric energy to supply power for the water electrolysis equipment, the water electrolysis equipment electrolyzes water to generate hydrogen and oxygen, and the hydrogen is directly conveyed to the fuel cell assembly and can generate electricity outwards; meanwhile, an excessive amount of hydrogen gas may be stored in the hydrogen storage unit to supply hydrogen gas to the fuel cell module by the time of the absence of the sun at night.
