Abstract
In the present study, a mathematical model has been formulated for the performance of polymer electrolyte fuel cells. Modify the concentration polarization equation using concentration coefficient that represents the characteristics of bipolar plate reactant distribution. The model predictions have been compared with experimental results and good agreement has been demonstrated for the cell polarization curves. The effects of operating parameters on the performance of fuel cells have been studied. Increases of operation pressure reduce the effect of temperature on the performance.
