<P>PROBLEM TO BE SOLVED: To provide a polymer electrolyte membrane stack that maintains form stability of a polymer electrolyte membrane in a high level by preventing the occurrence of wrinkles, unevenness, scratches, and peeling of the polymer electrolyte membrane during winding, transportation, and preservation, and further, has hardly occurrence of tube-like curling even if the environmental temperature and humidity during roll fabrication of the polymer electrolyte membrane stack and its operation using temperature and humidity are different greatly. <P>SOLUTION: In the polymer electrolyte membrane stack in which a polymer electrolyte membrane and a plastic film having no adhesive layer are laminated on at least one face of the polymer electrolyte membrane, the peeling strength of the polymer electrolyte membrane and the plastic film is ≤0.005 N/20 mm and the tensile modulus of elasticity of the plastic film is ≥0.1 GPa, and the thickness is ≥5 μm and ≤400 μm. <P>COPYRIGHT: (C)2011,JPO&INPIT |
