Abstract:
Disclosed are fuel cell systems, reinforced membrane electrode assemblies, and methods for fabricating a reinforced membrane electrode assembly. In an example, a disclosed method includes depositing an electrode ink onto a first substrate to form a first electrode layer, and applying a first porous reinforcement layer onto a surface of the first electrode layer to form a first catalyst coated substrate. The method also includes depositing a first ionomer solution onto the first catalyst coated substrate to form a first ionomer layer. A membrane porous reinforcement layer is applied onto a surface of the first ionomer layer to form a reinforced membrane layer.
