摘要

为研究质子交换膜燃料电池圆形双极板径向流场环形肋板上的孔道对电池性能的影响,借助多物理场仿真软件COMSOL Multiphysics对不同孔道数目的流道设计方案进行数值模拟。选定某一特定孔道数目之后,进一步研究孔道的形状尺寸对电池电化学性能和物质输运能力的影响。结果表明：增加环形肋板上孔道的数目有利于提升电池输出功率,采用长宽比为1.50~1.75的矩形孔道的燃料电池整体性能最优。

Abstract

In order to analyze the effect of the holes in the ring-shaped ribs on the performance of PEMFC with the circular bipolar plates, the schemes with different hole number are numerically simulated by COMSOL Multiphysics. After confirming the hole number, the shape and dimension of the rib holes are further researched. The results show that the hole number increasement can improve the output power of PEMFC. The rectangle shape of the hole with the length-width ratio between 1.5 and 1.75 has the best effect on the improvement of the PEMFC performance.
