In order to reduce the pollution caused by the use of traditional diesel generator vehicles, a hydrogen fuel cell generator vehicle system structure with multiple power generation and storage systems was designed. The flywheel energy storage system was used as the transitional power supply of the mains electricity and hydrogen fuel cell system, and the electric chassis battery was used as the backup starting power supply of hydrogen fuel cell system, improving the reliability and environmental protection of the vehicle. The control strategies of current sharing adjustment of multiple hydrogen fuel cell modules and multi-source coordinated operation of hydrogen fuel cell generator vehicle were proposed, achieving power improvement and uninterrupted output of the generator vehicle. Based on the study results, the first 400 kW hydrogen fuel cell generator vehicle at home and abroad was developed. The test and apply results showthat the design methodsproposed are correct.
