  • Membrane electrode assembly with integrated frame and fuel cell
    Patent number: 9859573
    Abstract: Disclosed is a membrane electrode assembly provided with a polymer electrolyte membrane; a catalyst layer (A) which is laminated onto one surface of the polymer electrolyte membrane; a gas diffusion layer (A) which is laminated onto the catalyst layer (A); a catalyst layer (B); and a gas diffusion layer (B). The outer circumferential section of the catalyst layer (A) is the membrane electrode assembly with an integrated frame which comprises a membrane electrode assembly that protrudes from the gas diffusion layer (A) and a frame adhered to the outer circumferential section of the catalyst layer (A), whereby said frame surrounds the edge of the membrane electrode assembly. The surface that is adhered to the frame in the outer circumferential section of the catalyst layer (A) comprises a plurality of cracks.
