Modelling a polymer electrolyte membrane fuel cell system with anodic and cathodic exhaust gas recirculation

A control-oriented model about PEM fuel cell system with anodic and cathodic exhaust gas recirculation is introduced in this paper. It contains anode and cathode system model, fuel cell stack model which contains water transport model, oxygen transport model, nitrogen transport model, voltage model and stack cooling system model. Only the water transport model is introduced here. Then the model is verified by experiment. Results show a good agreement between the simulated and measured cell voltages, cathode inlet molar water concentrations.
