A three-dimensional, single phase model of a proton exchange membrane fuel cell (PEMFC) with both the gas distribution flow channels and the Membrane Electrode Assembly (MEA) has been developed. A single set of conservation equations which are valid for the flow channels, gas-diffusion electrodes, catalyst layers, and the membrane region are developed and numerically solved using a finite volume based Computational Fluid Dynamics (CFD) technique. In this research, some parameters such as oxygen consumption, water production, temperature distribution, ohmic losses, anode water activity, cathode over potential and the fuel cell performance for straight single cell were investigated in more details. The numerical simulations reveal that these important operating parameters are highly dependent to each other and the fuel cell efficiency is affected by the kind of species distribution. So for especial uses in desirable voltages, for preventing from the unwilling losses, these numerical results can be useful. The important goal of this research is the investigation of the variation of bipolar plates width effect on the fuel cell performance compared with the conventional model, which is highlighted in the results section with more details.Finally the numerical results of proposed CFD model have been compared with the published experimental data that represent good agreement.
