Patent ID: 7955750

Claim:
A membrane electrode assembly, comprising: a membrane layer; a cathode catalyst layer adjacent to a surface of the membrane layer; an anode catalyst layer adjacent to an other surface of the membrane layer, wherein the membrane layer is disposed between the cathode catalyst layer and the anode catalyst layer; an adhesive layer adjacent to the other surface of the membrane layer, wherein the adhesive layer abuts a surface of the anode catalyst layer, wherein a portion of the adhesive layer infiltrates into the anode catalyst layer to form an adhesive infiltration layer; and a subgasket layer having an edge portion, wherein the subgasket layer is adjacent to a surface of the adhesive layer, wherein the adhesive layer is disposed between the subgasket layer and the membrane layer and the subgasket layer extends over and is adjacent to a planar surface of a portion of the anode catalyst layer; wherein the cathode catalyst layer and anode catalyst layer extend along a length of the membrane layer relative to the edge portion of the subgasket layer, wherein the cathode catalyst layer extends a greater length along the length of the membrane layer than the anode catalyst layer relative to the edge portion of the subgasket layer, and wherein the adhesive infiltration layer is disposed between the anode catalyst layer and the subgasket layer.
