The results show that when the cathode humidified temperature increase, the humidification of membrane and fuel cell performance improved at lower current density, while the saturation in diffusion layer increase and the performance decreases at higher current density. Humidification of membrane and fuel cell performance improved when the anode humidified temperature increase, the saturation in diffusion layer decrease and fuel cell performance improved when the fuel cell working temperature increase, the resistance of diffusion layer decrease and the performance improved when the porosity largen. At last, the simulation results are compared with the experimental results and they are basically the same.
