NOVELTY - A membrane electrode assembly comprises a fluid impermeable feed region circumscribing a porous membrane support region, at least one of feed region and the membrane (4) support region formed at least partially by a radiation-cured structure. The feed region is a solid, planar sheet.    USE - For fuel cell (claimed).    ADVANTAGE - The membrane electrode assembly minimizes production waste; is cost-effective; facilitates alignment of the electrolyte membrane and subgasket within the fuel cell; is mechanically stable; and militates against formation of stress risers within the fuel cell at the junction between subgasket and the electrolyte membrane.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for following:    (1) a fuel cell comprising the membrane electrode assembly, where the membrane support region imbibed with ionomer to form an electrolyte membrane, and pair of electrodes disposed on opposing sides of the electrolyte membrane; a pair of gas diffusion media, each of the gas diffusion media disposed on one of electrodes; and a pair of electrically conductive fuel cell plates, where the subgasket, electrolyte membrane, electrodes, and gas diffusion media are disposed between the fuel cell plates; and    (2) fabricating a membrane electrode assembly involving providing a volume of radiation-sensitive material and at least one radiation source; placing a first mask between the at least one radiation source and the radiation-sensitive material, where the first mask having at least one aperture; exposing the radiation-sensitive material to radiation beams to form a membrane support region with a porous radiation-cured structure and a feed region circumscribing the membrane support region; and removing an uncured volume of the radiation-sensitive material from the membrane electrode assembly. The radiation-sensitive material is one of liquid photomonomer and solid radiation-sensitive polymer. The feed region is fluid impermeable. The method further involves applying ionomer to the membrane support region to form an electrolyte membrane; coating the faces of the electrolyte membrane with a catalyst ink, and drying the catalyst ink to form a pair of electrodes on the electrolyte membrane.
