A Computational Fluid Dynamics (CFD) Investigation of two PEM Fuel Cells with Straight Single-Channel(SC): SC-40mm and SC-50mm

Abstract

The (PEM) fuel cell with straight single-channel is composed of current collectors (CCs), catalyst layers (CLs), gas diffusion layers (GDLs) and membrane. There are a large number of design parameters which can influence the performance of the (PEM) fuel cell system. In this study, the influences of geometric parameters are studied and developed. The comparison of polarization curve and gas species distribution within the two cells as well as the temperature distribution are presented and discussed. The straight single-channe1-50mm (SC-50mm) showed better in performance than single-channel-40mm (SC-40mm) by 83%.
