Abstract:
Disclosed are methods for fabricating a reinforced membrane electrode assembly having one or more freestanding external reinforcement layers. The method comprises providing a freestanding external reinforcement layer, and depositing a catalyst solution and membrane solution onto at least a portion of the freestanding external reinforcement layer.

Abstract:
A method of making an electrode ink containing nanostructured catalyst elements is described. The method comprises providing an electrocatalyst decal comprising a carrying substrate having a nanostructured thin catalytic layer thereon, the nanostructure thin catalytic layer comprising nanostructured catalyst elements; providing a transfer substrate with an adhesive thereon; transferring the nanostructured thin catalytic layer from the carrying substrate to the transfer substrate; removing the nanostructured catalyst elements from the transfer substrate; providing an electrode ink solvent; and dispersing the nanostructured catalyst elements in the electrode ink solvent. Electrode inks, coated substrates, and membrane electrode assemblies made from the method are also described.
