摘要： A membrane electrode assembly with frame includes a membrane electrode assembly 2 in which an electrolyte membrane 11 is held between a pair of electrode layers 12, 13; and a resin frame 1 disposed around the membrane electrode assembly 2. The frame 1 includes an opening 1A in which the membrane electrode assembly 2 is disposed, a step 1B that is formed along an edge of the opening, and an inner peripheral portion 1C that is deviated to one side of the frame due to the step 1B. The outer peripheral portion of the membrane electrode assembly 2 is joined to the inner peripheral portion 1C on one side opposite the deviated side. In the frame 1, the inner peripheral portion 1C, to which the membrane electrode assembly 2 is joined, has a thickness approximately equal to the thickness of the body, while the step 1B has a larger thickness. This configuration ensures the strength against a force in the thickness direction and thereby prevents the frame 1 from being damaged.
