High power density enhances polymer electrolyte fuel cell with widely varied applications. Our investigation focused on the refinement of the reactant gas flow field at the bipolar plate in order to increase the fuel cell performance. Applying a porous material to the reactant gas flow field is one possible method. Expected advantages of a porous flow field are an increase in reactant gas diffusivity and electron conductivity allover the electrode. An investigation was carried out to evaluate the feasibility of a porous flow field. The Lattice Boltzman simulation indicated that surface wettability and pore structure control have prospect of gas and water flow field separation. The experiment of porous flow field showed same level performance of channel type.
