Abstract

A numerical study on the performance of a PEMFC was performed by using a CFD-ACE+commercial program. The effects of width, hight and shape of channel cross section and mass flow rate were investigated. In order to check the validity of the simulation, comparisons were carried out between predictions and experimental data available in the literature and shows the reasonable agreement. It is found that only the width of channel is strongly related to the performance of a PEMFC, while other factors have no marked effects.
