Abstract: A fuel cell, a reinforced membrane electrode assembly and a method of fabricating a reinforced membrane electrode assembly. The method comprises depositing an electrode ink onto a first substrate to form a first electrode layer, applying a first porous reinforcement layer on a surface of the first electrode layer to form a first catalyst coated substrate, depositing a first ionomer solution onto the first catalyst coated substrate to form a first ionomer layer, and applying a membrane porous reinforcement layer on a surface of the first ionomer layer to form a reinforced membrane layer.
