Abstract

A new flow channel with an extended area is proposed in this paper. The length of the extended area is 1, 2, and 4 mm, respectively. A three-dimensional isothermal steady-state model is established by COMSOL software. The results demonstrate that the performance of PEMFC with the novel flow channel is superior to that with the traditional straight channel. And the optimal extended length is 2 mm. At high current density, the extended channel can contribute to more uniform oxygen distribution and improve the removal of water. Increasing the number of extended areas after determining the optimal extended length will enhance fuel cell performance even more. The channel with double extended regions can increase the peak power density of PEMFC by 18.44% when compared to the traditional straight channel.
