质子交换膜燃料电池冷启动性能影响因素分析

Influence factors of cold start performance of PEMFC

质子交换膜燃料电池(PEMFC)的冷启动性能与初始水含量、启动模式、启动温度等密切相关。从电池内部水结冰/解冻过程,电池的不同启动模式,电池内水的结冰位置等方面较详细地阐述了它们对电池性能的影响,对学者们的研究成果进行了总结归纳,就电池冷启动后续研究方向提出了建议。

The cold start performance of proton exchange membrane fuel cell (PEMFC) is closely related to initial water content, start-up mode and start-up temperature. Some influence factors with respect to fuel cell performance were described, including water freezing or thawing process within the fuel cell stack, different battery start-up mode, battery water ice location, etc. The author summarized the research results of the previous scholars, and pointed out the research focus of the battery cold start in the future.
