摘要
针对不同空气流向对电堆性能的影响进行ANSYS/Fluent仿真分析,开展实验研究,在环境温度、风扇转速等外界条件不变的情况下,测量两种不同工作温度下外部风扇"吸风"与"吹风"两种空气流动方式对电堆总输出和各单电池输出特性的影响。结果表明:采用"吸风"方式供应空气(即正向流动)时,电堆的均匀性和稳定性等性能明显较好。考虑到电堆使用寿命,空冷质子交换膜电堆采用空气正向流动方式更为有利。
ANSYS/Fluent was used to simu｜ate and ana｜yze the effect of different air flow direction on performance of the stack. The output performance of the stack and each cell under different air flow directions were measured in both low and high operation temperatures with external conditions such as the ambient temperature and the fan speed unchanged. The results showed that the uniformity, stability and service life of the stack under positive air flow are much better than the reverse flow.
