CURABLE SUBGASKET FOR A MEMBRANE ELECTRODE ASSEMBLY

摘要

A subgasket for a membrane electrode assembly is deposited on a surface of a MEA component and cured in situ. A membrane electrode subassembly includes a polymer electrolyte membrane, a gas diffusion layer and a catalyst layer between the polymer electrolyte membrane and the gas diffusion layer. The membrane electrode subassembly includes a subgasket, disposed over one or more components of the membrane electrode subassembly. The subgasket is made of a layer of material that is depositable and curable in situ. A peripheral edge of the gas diffusion layer overlaps the subgasket.
