Performance Analysis of PEMFC with Single-Channel and Multi-Channels on the Impact of the Geometrical Model

A low-performance fuel cell significantly hinders the application and commercialization of fuel cell technology. Computational fluid dynamics modeling could predict and evaluate the performance of a proton exchange membrane fuel cell (PEMFC) with less time consumption and cost-effectiveness. PEMFC p...
