The performance of the Proton Exchange Membrane Fuel Cell (PEMFC) is considerably influenced by the different parameters like, geometrical, environmental and flow parameters. The uniform distribution of the reactant gases over the active area are carried out by the flow channels in the PEM fuel cell. In this numerical analysis, the PEM fuel cell single flow channel configuration with different channel size (0.5 mm× 0.5 mm, 1 mm ×1 mm, 1.5 mm × 1.5 mm, 2.0 mm × 2.0 mm) is analyzed for various cell potentials to evaluate the various performance parameters like, anode hydrogen concentration, cathode water concentration, cathode oxygen concentration, membrane current density, Pressure and velocity of flow gases at gas diffusion layer. The entire comprehensive three dimensional models of the four different channel sizes of PEM fuel cell single flow channel configuration with the similar size of rib and channel length were designed and analyzed by means of a standard modeling and analysis software. From this numerical analysis, different performance parameters of the PEM fuel cell with four different flow channels were measured and the obtained results were compared with each other.
