The performance of the polymer electrolyte membrane fuel cell (PEMFC) mainly depends on water and thermal behavior in the fuel cell systems. The PEMFC model structure that describes water transport phenomena, thermal properties, and electrochemical reactions is developed. We considered that the PEMFC system consists of three physically distinctive parts; the anode channel, the cathode channel and the fuel cell MEA. The mass conservation law and the energy conservation law are adopted to each physical part as a control volume and the steady-state electrochemical model for the membrane is adopted to the fuel cell MEA control volume for the output voltage. For a preliminary study on modeling of the PEMFC, the physical and the electrochemical phenomena of the control volume were mathematically described.
