<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a proton conductive film which is used for a solid state polymer-type fuel cell, suitable to the use for electrolytes, and has a superior proton conductivity and mechanical strength. <P>SOLUTION: The method of manufacturing the proton conductive film is characterized in that a polymer having an acidic ion-conductive component and an additive which can perform an acid-base mutual action with respect to the ion conductive component are dispersed or dissolved in a solvent, the dispersion liquid or the dissolution liquid is cast to be formed in a film state, then the formed body is immersed in water to extract and remove the additive or residual components. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
