    Abstract:

    To solve the problems of low output efficiency and short life of single-stack fuel cell systems， the energy management strategy （EMS） and control strategy of the multi-stack fuel cell （MFC） system for vehicles were studied in this paper. A multi-level EMS was proposed， in which the first-level EMS adaptively distributed energy between the MFC system and the power battery system based on working conditions， and the second-level EMS used an objective optimization function that took into account efficiency and life to optimize the distribution of each power output of the stack. The results show that compared with the single-stack fuel cell system， the fuel economy of the MFC system can be increased by 4% and the life performance of the MFC system can also be improved.
