Abstract

A mixed-domain, two-phase flow, non-isothermal model is developed to study the water transport phenomena, which has significant effects on the performance of PEM fuel cells. Modelling results show that: the total water concentration is decreasing along the channel in anode, while it is increasing in cathode, flooding is most likely to occur at the end of cathode flow channel; liquid water in cathode GDL presents opposite distribution at high current density and low current density, the saturation of liquid water is decreasing from inner side to outer side across the GDL at low current density while it is increasing at high current density.
