PROBLEM TO BE SOLVED: To provide an adhesive for a fuel cell separator, excellent in adhesion with a fuel cell separator, heat resistance and stress relaxing properties against an external load.SOLUTION: An adhesive for a fuel cell separator contains a (meth)acrylic ester resin that includes, as a monomer component, an aromatic vinyl compound, alkyl acrylate and alkyl methacrylate, and has a weight average molecular weight of 100,000-1,000,000. In the adhesive for a fuel cell separator, each of concentrations of NHand Clis 0.5 ppm or less, the concentrations being measured by ion chromatography after 10 g of the adhesive for a fuel cell separator has been stored in 50 ml of pure water at 120°C for 20 hours.SELECTED DRAWING: None |
