PROBLEM TO BE SOLVED: To provide a resin composition for solid polymer fuel cell sealant having high adhesiveness even to a non-polar material and preventing deterioration by moisture while suppressing reduction of adhesiveness under high temperature environment.SOLUTION: There is provided a resin composition for solid polymer fuel cell sealant containing (a1) styrene of 5 mass% or more and (b) a copolymer resin by copolymerizing raw material components containing glycidyl (meth)acrylate of 20 mass% or less and having weight average molecular weight of 150,000 or more. Preferably it has a constitution further containing (c) one or more kind of other polymerizable monomer selected from hydroxyalkyl (meth)acrylate and alkyl (meth)acrylate in the raw material components.SELECTED DRAWING: None |
