英文摘要：

A two-dimensional, single phase, multi-component modei was developed for the cathode of PEM fuel cell using the inerdigitated gas distributor. The gaseous transport process and electrochem-ical reaction were numerically simulated. The governing equations including continuity equation , Darcy s law and the advection-diffusion equations were solved by the finite-volume method. The model was used to investigate the performance of PEM fuel cell using the interdigitated gas distributor and the conventional distr...
