摘　　要：本文通过理论分析质子交换膜燃料电池堆各种方式的散热量,得到燃料电池堆散热主要由冷却循环水交换出电池。同时组装46片电堆,搭建实验平台,根据实验数据,对这一结论进行了进一步验证。结果表明:稳态时空气流量对电堆换热量可以忽略不计,约97%的产热量由冷却水通过热交换移出电堆。Based on the theoretical analysis of heat released in PEMFC stack, it is found that heat generated in the PEMFC stack heat was mainly removed by coolant water. Meanwhile, a 46 single cell stack is designed and assembled to verify the results experimentally. The conclusion is that the effect of air flux on the heat removal in the stack could be neglected, about 97% of the heat generated in the PEMFC stack is removed by coolant water.
