    摘要： A method of making a membrane electrode assembly is provided. The method includes providing a non-porous polymeric substrate which has sufficient structural integrity and elastic deformation such that no significant deformations occur during processing to facilitate reuse. The substrate is optionally formed into a loop for continuous processing. A slurry is formed which includes an ionically conductive material, an electrically conductive material, a catalyst, and a high boiling point solvent. The slurry is applied onto the non-porous polymeric substrate, for example, in a pattern of discrete regions. The slurry is dried to form decals. The decals are bonded to a membrane and then the substrate is peeled from the decal in a substantially undamaged condition so that it may be reused.

    摘要： A technique for fabricating an MEA. The technique includes providing a polymer electrolyte proton conducting membrane, and then spraying a catalyst ink directly on the membrane to form a catalyst layer. In one embodiment, the catalyst ink includes the proper ionomer to carbon ratio, such as 0.8/1, for the desired fuel cell performance. In another embodiment, the catalyst ink includes too little ionomer for the proper ionomer to carbon ratio for the desired fuel cell performance. An ionomer layer is sprayed on the membrane before the catalyst layer to provide the proper final ionomer to carbon ratio.
