Abstract

Abstract: The improvement of proton exchange membrane fuel cell (PEMFC) performance depends on the ability of mass transfer. Based on the theoretical analysis, the investigation focusing on the enhancement of mass transfer has been carried out using three dimension model through two methods, adding blocks in gas channel and perforation of gas diffusion layer (GDL). The results show that the two methods above would effectively strengthen the ability of mass transfer and improve the performance of the PEMFC. What's more, extra parasitic power would be needed and the effect of adding blocks should be comprehensively evaluated.

Key words: proton exchange membrane fuel cell, adding blocks, perforation of gas diffusion layer, mass transfer enhancement

摘要： 传质问题制约着燃料电池性能的提高。通过理论分析、Fluent模拟，针对质子交换膜燃料电池流道中加凸台和电极扩散层开孔两种方法，分别研究其对强化电池内部传质的效果。结果表明，上述两种方式均能有效强化电池内部传质，提高电池性能。但是加凸台增加了风机的寄生功率，综合性能提升不显著。
