Abstract

Water and heat management play a very important role on the performance of PEM fuel cell. In this paper, a two-phase flow model is presented to investigate the transport phenomenon of the water and the temperature in the membrane and the cathode of PEM fuel cell. The distributions of the water and the temperature in the membrane and the cathode catalyst layer are analyzed. Simulation results show that the liquid water in the cathode and the water content in the membrane increase with the increase of humidification temperature; along the gas channel, the temperatures in the membrane and the cathode catalyst layer decrease, but water concentration increases; in the transverse section of the membrane and the cathode catalyst layer from the interface with the anode to the interface with the cathode diffusion layer, the temperature increases firstly, and then decreases.
