Abstract:

A two-dimensional, two-phase across the channel computational model of proton exchange membrane fuel cell(PEMFC) is established.It accounts for all major transport phenomena, including water and proton transport through the membrane, electrochemical reaction, transport of electrons, transport and phase change of water in the gas diffusion electrodes, and diffusion of multi-component gas mixtures in the electrode.The model can be used to research the effects of flow field, diffusion layer, catalyst layer and membrane on the performance of PEMFC, so the cell structure can be optimized.
