<P>PROBLEM TO BE SOLVED: To obtain a proton-conductive resin composition which has excellent adhesiveness and is useful for a fuel cell, and to prepare a heat-fusible proton-conductive film. <P>SOLUTION: The proton-conductive resin composition comprises 60-10 wt.% of an aromatic polyether (A) having 100-220°C flow starting temperature and 40-90 wt.% of a protonic acid group-containing aromatic polyether (B). Preferably, the aromatic polyether (A) contains a repeating structural unit of formula (1) (A<SB>1</SB>and A<SB>2</SB>are each a direct bond, CH<SB>2</SB>, C(CH<SB>3</SB>)<SB>2</SB>, C(CH3)<SB>2</SB>, O, SO<SB>2</SB>or CO: (g), (h) and (i) are each 0 or 1; each hydrogen atom of an aromatic ring may be substituted with a C<SB>m</SB>H<SB>2m+</SB>1 ((m) is an integer of 1-10), Cl, F, CF<SB>3</SB>or CN) and has no protonic acid group. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
