Abstract

In this study, a BEKKTECH BT-552 PEMFC test station was used in order to investigate the effect of a three different gas flow fields (with w/a ratios of 1, 1.05 and 1.2) on fuel cell performance at two different system backpressures of 70 kPa ( Test no. 1) and 30 kPa (Test no.2), respectively. The nominal efficiency of the PEM fuel cell was  an arbitrary value, located in the domain 0.76 – 0.46 for Test no. 1 and 0.75 – 0.39 for Test no. 2 in the case of the optimized flow field model M3, with w/a ratio of 1.05.
