Abstract: The present invention provides a support film for solution film forming, said support film combining polymer solution leakage properties during a solution film forming step, early separation resistance during a drying step and wetting step, and easy release properties when intentionally separating a polymer film. Provided is a support film for solution film forming, said support film being formed by introducing fluorine atoms to at least one surface of a base film that is formed from one or more types of polymers selected from the group consisting of polyethylene, polypropylene, polyethylene terephthalate, polybutylene terephthalate, polyethylene napthalate, polyphenylene sulphide, polysulfones, polyether ketone, polyether ether ketone, polyimides, polyetherimide, polyamides, polyamide-imides, polybenzimidazoles, polycarbonates, polyarylates, and polyvinyl chloride. Therein, the ratio, measured by X-ray photoelectron spectroscopy, of the number of fluorine atoms/the number of carbon atoms in the surface to which the fluorine atoms are introduced, i.e. the modified surface, is 0.02-0.8, inclusive.

Abstract: A polyelectrolyte material, a polyelectrolyte component, a membrane electrod e composite body, and a polyelectrolyte type fuel cell. The above material is used in the above fuel cell or the like as the above component or the composite body. In addition to a conventional fuel cell using hydrogen gas a s a fuel, a direct type fuel cell using methanol as a fuel is also attracting our attention. Although a material having performances excellent in proton conductivity and excellent in methanol shielding property and mechanical strength is required for the direct type fuel cell, the conventional materia l is short of satisfying the requirements. The above material is immersed in 1 - 30 wt.% methanol solution at 40-80~C for 12 hours, and then is immersed in pure water at 20~C for 24 hours to obtain a polyelectrolyte material having Rw, represented by the following expression, of 75-100 wt.% and an ionic radical in a water-containing state immediately after pulled up, whereby the above problems are solved. Rw= [Wnf/(Wfc+Wnf)] ~ 100, in the expression, Wnf : non-frozen water amount per weight one gram of dry polyelectrolyte material Wfc: low-melting point water amount per weight one gram of dry polyelectroly te material
