摘要：
High power hydrogen fuel cell commercial vehicles is the focus to promote the application of hydrogen energy and the design of an efficient hydrogen recirculation system is crucial for the performance of fuel cell vehicles. In this paper, four hydrogen recirculation schemes are analyzed for a 200 kW high power fuel cell vehicle system. The performance evaluation index of the hydrogen recirculation device is established, and the characteristics of each hydrogen recirculation scheme are analyzed from different aspects based on theoretical analysis and CFD simulation. The results show that the power consumption of the hydrogen pump can be reduced significantly with the combination of the ejector and hydrogen pump. Compared with the hydrogen pump mode, the maximum power of the hydrogen pump in parallel mode is reduced by 81.4%, and the maximum power in series mode is reduced by 85.3%. The analysis of the contribution rate and power consumption of hydrogen recirculation shows that the series mode of ejector and the hydrogen pump can make better use of the performance of ejector. © 2022, Society of Automotive Engineers of China.
