摘要
针对一种基于自回水双极板的无增湿质子交换膜燃料电池,设计了阴极集流板的冷却水流道,使阴极集流板具有为反应气体增湿、回收反应生成的水和冷却燃料电池三方面的功能。利用CFD技术对一个由21个单电池组成的无增湿燃料电池堆冷却水道内部冷却水流动情况进行了数值模拟,分析了电堆水道内部压力和速度的分布情况。最后对电堆冷却水流道进出口压差进行了测试,测试结果与计算结果能较好吻合。
A kind of coolant flow field in the cathode bipolar plate was designed for a non-humidifi- cation PEMFC based on water self-retrieving bipolar plate, which could humidify the reactant gas, retrieve excess water in the fuel cell and chill down the fuel cell. Coolant flow inside a non humidification PEMFC stack composed of 21 single fuel cells was numerically simulated by CFD technology and the distribution of pressure and velocity was calculated. Eventually, the pressure difference between inlet and outlet of the coolant flow field was tested and the caleulation results was coincided with the experimental results.
