<P>PROBLEM TO BE SOLVED: To provide an electrolytic membrane acting in unhumidified condition by producing an organic-inorganic hybrid membrane using phosphoric acid or phosphorous acid as a proton source by a simple membrane-producing method. <P>SOLUTION: The composition for forming a self-supporting solid membrane comprising the phosphoric acid or the phosphorous acid, and silsesquioxane is regulated so that the molar ratio of the phosphoric acid or the phosphorous acid to the silsesquioxane or a silane coupling agent may be 3≥P/Si≥0.1 to form the self-supporting solid membrane, or the weight ratio of zeolite to the phosphoric acid may satisfies the relations of 40%≥zeolite/H<SB>3</SB>PO<SB>4</SB>or H<SB>3</SB>PO<SB>3</SB>≥3%. More preferably, one or more of a diepoxy compound, a diamine compound, an acid anhydride, a diisocyanate compound, a dithiocyanate compound and a diisothiocyanate compound in a molar ratio of 2.5≥whole compounds/Si≥0.1 are mixed with the silsesquioxane. <P>COPYRIGHT: (C)2009,JPO&INPIT |
