摘要： A fuel cell comprises a cathode gas diffusion layer, a cathode catalyst layer, an anode gas diffusion layer, an anode catalyst layer and an electrolyte. The diffusion resistance of the anode gas diffusion layer when operated with anode fuel is higher than the diffusion resistance of the cathode gas diffusion layer. The anode gas diffusion layer may comprise filler particles having in-plane platelet geometries and be made of lower cost materials and manufacturing processes than currently available commercial carbon fiber substrates. The diffusion resistance difference between the anode gas diffusion layer and the cathode gas diffusion layer may allow for passive water balance control.

摘要： One exemplary embodiment includes a fuel cell comprising a polymer electrolyte membrane sandwiched between an anode and a cathode, a gas diffusion layer disposed over each of the cathode and the anode, a gas flow distributor layer disposed over the gas diffusion layer on both the anode and cathode sides, and optionally a coolant plate disposed over the gas flow distributor layer. The thermal resistance of the combined gas diffusion layer and gas flow distributor layer on the anode and/or cathode side is sufficient to allow the cathode catalyst layer to operate at an elevated temperature to effectively evaporate water produced at the cathode.
