In this study, a non-isothermal, two-phase, one-dimensional, and steady state proton exchange membrane (PEM) fuel cell model is developed to investigate the detailed electrode kinetics in the anode and cathode catalytic regions and the effects of these reaction mechanisms on the performance of a PEM fuel cell. Langmuir-Butler-Volmer (LBV) type reaction rate expressions are suggested for both anode and cathode electrochemical reactions. A two-phase energy balance approach is used to catch the thermal transport phenomena in cases when there is a significant temperature difference between the fuel cell temperature and the reactants inlet temperatures like during cold start-up.
