Membrane electrode assembly having low surface ionomer concentration
Abstract:
A membrane electrode assembly (MEA) comprises a polymer electrolyte membrane having at least one electrode layer on each of the opposing sides of the membrane. The electrode layer comprises a catalyst, an electrically conductive particulate material and an ionomer binder. The ionomer binder concentration on the exterior surface of the MEA is lower than the ionomer binder concentration near the electrode membrane interface. The electrode layer is formed by casting and drying a solvent ink layer between a nonporous release surface and a porous releasable decal.
