Abstract
In an MEA member constituted by a polymer electrolyte membrane-electrode assembly (MEA) and a frame and in a polymer electrolyte fuel cell including this MEA member, the MEA and the frame can be easily separated from each other without using any special tool. An MEA memberincludes an MEAand a plate-shaped resin frame, and a separating portion for separating the MEAfrom the frameis formed in the MEA member. The MEAincludes a polymer electrolyte membraneand a pair of electrodesandrespectively disposed on both main surfaces of the polymer electrolyte membrane. The framesandwiches and holds a peripheral portion of main surfaces of the MEAsuch that the MEAis located inside the frame. The separating portion is a broken-line cutoff lineformed on the frameto divide the frameinto two or more parts or a partial sandwiching portionlocated at an inner peripheral portion of the frameto partially sandwich the peripheral portion of the MEA
