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.
