摘要： Provided is a solid polymer electrolyte type fuel cell having high durability. The fuel cell comprises a stack of single cell modules, each including an electrolyte membrane-electrode-frame assembly and a pair of separators. The electrolyte membrane-electrode-frame assembly includes a catalyst layer-attached electrolyte membrane having a polymer electrolyte membrane, an anode catalyst, and a cathode catalyst, a frame that is disposed at a peripheral portion of the catalyst layer-attached electrolyte membrane and has a rectangular inner periphery, and a pair of gas diffusion layers that are disposed on both surfaces of the catalyst layer-attached electrolyte membrane. The gas diffusion layers were disposed to cover an inner peripheral portion of the frame, respectively. A thickness of at least a part of a corner portion of the inner peripheral portion is smaller than a thickness of a linear side portion of the inner peripheral portion of the frame.
