摘要：A three-dimensional, steady-state non-isotherm mathematical model for proton exchange membrane fuel cell is developed. The model takes into accounts simultaneously the mass, momentum, energy, species, charge conservation equation and combines electrochemistry reaction inside the cell. The simulation results show that it is easy to improve the fuel cell performance for higher porosity in the diffusion layer, because of the benefit of speeding the gas diffusion, reducing the concentration grads of gas, depressing the ridge board domino offect and falling current density grads.
