Abstract

A two-dimensional mathematical model is used to investigate the performance and transport characteristics of PEM fuel cells with different membrane thicknesses. The overall cell performance of three cases are presented and compared. In addition, the local temperature, liquid water saturation, water content and current density distributions are analyzed and compared. Results show that performance increases with decreasing membrane thickness and the local transport characteristics is also significantly affected. The ohmic loss is mainly caused by the proton transport process inside fuel cell. And a thinner membrane can enhance water back diffusion process in the membrane which is beneficial to the water management at the anode side.
