<P>PROBLEM TO BE SOLVED: To prevent a laminate film which prevents sufficiently the generation of wrinkles or peeling marks in peeling a support substrate, and can form a polyelectrolyte film excellent in appearance, and a keeping method and a conveying method of the polyelectrolyte film using a shape of the laminate film. <P>SOLUTION: The laminate film is laminated by the polyelectrolyte film containing a polyelectrolyte, and a polyolefin film, the polyolefin film being a film composed of a polyethylene resin and/or a polypropylene resin. Preferably, the laminate film is a film of a long shape and has a shape of a scroll scrolled by a core. The polyelectrolyte film obtained by peeling the polyolefin film from the laminate film can be used suitably for a polymer electrolyte fuel cell. <P>COPYRIGHT: (C)2010,JPO&INPIT |
