<P>PROBLEM TO BE SOLVED: To provide a forming method of an electrolyte film for a fuel cell in which power generation performance can be improved while the productivity of an electrode membrane junction for the fuel cell is maintained. <P>SOLUTION: In the forming method of the electrolyte film for the fuel cell, the electrolyte membrane 24 in an undried state is tentatively dried at a temperature not exceeding the decomposition temperature of a solid polymer of a hydrocarbon group, steam is introduced into the electrolyte membrane 24 by arranging the tentatively dried electrolyte membrane 24 in the steam, thereby the steam is introduced into the electrolyte membrane 24, a solvent 41 in the electrolyte membrane 24 is removed, and the electrolyte memrane 24 after the solvent 41 has been removed is then completely dried at the temperature not exceeding the decomposition temperature of the solid polymer hydrocarbon group. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
