Fuel cell membrane electrode assembly

A fuel cell membrane electrode assembly, the membrane electrode assembly comprising:

• a solid polymer electrolyte membrane;
• a first electrode provided on one surface of the solid polymer electrolyte membrane, the first electrode including a first catalyst layer and a first gas diffusion layer;
• and
• a second electrode provided on another surface of the solid polymer electrolyte membrane, the second electrode including a second catalyst layer and a second gas diffusion layer,
• wherein a surface size of the first gas diffusion layer is larger than a surface size of the second gas diffusion layer;
• a frame shaped protection member is formed around an outer marginal portion of the solid polymer electrolyte membrane extending outward beyond an outer end of the second gas diffusion layer;
• a cushioning member is provided between the outer marginal portion of the solid polymer electrolyte membrane and the protection member;
• and
• the cushioning member has an overlapped portion overlapped on an outer marginal end of the second gas diffusion layer.
