摘要： A method of transferring nanostructured thin catalytic layers to a gas diffusion layer and thus making a catalyst coated diffusion media is described. The method includes treating the gas diffusion layer with a temporary adhesive to temporarily increase the adhesion strength within the microporous layer and to carbon fiber paper substrate, transferring the nanostructured thin catalytic layer to the microporous side of a gas diffusion media layer. The nanostructured thin catalytic layer can then be further processed, including adding additional components or layers to the nanostructured thin catalytic layer on the gas diffusion media layer. Preparation of catalyst coated diffusion media and a catalyst coated diffusion media based membrane electrode assembly (MEA) are also described.

摘要： A fuel cell including a water blocking layer positioned between anode gas flow channels and a gas diffusion media. The blocking layer prevents water from propagating through the gas diffusion media layer and entering the anode flow channels, while allowing gas from the flow channels to flow through the diffusion media layer to the membrane. A water accumulation channel can be provided around the perimeter of the gas diffusion media layer where blocked water is accumulated, and allowed to expand during cell freezing. A porous capillary wick can be provided in the accumulation channel for wicking water to the inlet end of the flow channels where it is used to humidify the anode gas coming into the fuel cell. The wick can have a tapered configuration so that it has a larger diameter at the gas input end of the flow channels.
