摘　　要：文章对上汽燃料电池发动机进行了-20℃冷启动试验研究。基于现有系统架构和控制策略,利用环境仓内开发试验台架,成功完成-20℃冷启动,启动时长为40 s,电堆单池一致性满足要求,无明显单低和反极现象。同时对启动过程中的能量分配和停机吹扫进行了分析,为后续-30℃冷启动策略开发提供宝贵经验。This paper introduces the rapid start - up experiment of SAIC fuel cell engine on test bench. Based on existing system architecture and control strategy, by using the test bench in envi- ronmental storehouse, the system finished -20 ℃ cold start -up experiment successfully and the time is 40 s. There is no obvious low cell voltage and contra polarization phenomenon, which means good consistency. Meanwhile, power distribution and stop process strategy are analyzed, which support ex- perience for follow -up -30 ℃ strategy development.
