摘要： An MEA for a fuel cell that employs multiple catalyst layers to reduce the hydrogen and/or oxygen partial pressure at the membrane so as to reduce the fluoride release rate from the membrane and reduce membrane degradation. An anode side multi-layer catalyst configuration is positioned at the anode side of the MEA membrane. The anode side multi-layer catalyst configuration includes an anode side under layer positioned against the membrane and including a catalyst, an anode side middle layer positioned against the anode side under layer and not including a catalyst and an anode side catalyst layer positioned against the anode side middle layer and opposite to the anode side under layer and including a catalyst, where the amount of catalyst in the anode side catalyst layer is greater than the amount of catalyst in the anode side under layer.

摘要： A fuel cell including an anode-side catalyst coated membrane and a cathode-side catalyst coated membrane. At least a portion of a reduced-permeability layer is disposed between the ionically conductive membrane and the anode-side and cathode-side gas diffusion media, wherein the reduced-permeability layer is formed of a material that has a permeability that is less than a permeability of the ionically conductive member. The reduced-permeability layer may also be formed of a material that is softer than the ionically conductive membrane.
