Three-Dimensional Computational Fluid Dynamic Study of Effect of Different Channel Geometries on PEM Fuel Cell Performance

A full-three-dimensional computational fluid dynamics (CFD) analysis based on finite volume method was developed to study the performance of Proton exchange membrane fuel cells (PEMFCs) with different channel geometries at high operating current densities. This model was used with single straight channel geometry. This general model accounts for the major transport phenomena and the effect of different gas channelshoulder geometries such as circular shape for gas channel on cell performance for example: current density, power density, protonic conductivity, ohmic loss and species distribution which discussed in more details.
