Patent number: 9780399Abstract: An electrode assembly and a method of making an electrode assembly. One embodiment of the method includes coating an ionomer solution onto a catalyst coated diffusion media to form a wet ionomer layer, and applying a porous reinforcement layer to the wet ionomer layer such that the wet ionomer layer at least partially impregnates the reinforcement layer. Drying the wet ionomer layer with the impregnated reinforcement layer and joining it to the catalyst coated diffusion media forms an assembly that includes an integrally-reinforced proton exchange membrane layer. This layer may be additionally joined to other ionomer layers and other catalyst coated diffusion media such that a membrane electrode assembly is formed.Type: GrantFiled: March 30, 2012Date of Patent: October 3, 2017Assignee: GM Global Technology Operations LLCInventors: Scott C.
