<P>PROBLEM TO BE SOLVED: To provide an addition reaction-curable silicone rubber adhesive composition for a polymer electrolyte fuel cell capable of keeping adhesive force over long period even under such a severe condition as exposed to hot water. <P>SOLUTION: This addition reaction-curable silicone rubber adhesive composition for the polymer electrolyte fuel cell comprises (A) an epoxy group-containing isocyanurate compound, (B) an organopolysiloxane having at least two alkenyl groups each bonding to a silicon atom, (C) an organohydrogenpolysiloxane having at least two SiH groups, (D) a platinum group metal-based catalyst, (E) an organopolysiloxane resin having an SiO<SB>4/2</SB>unit and an R<SP>4</SP><SB>3</SB>SiO<SB>1/2</SB>unit (R<SP>4</SP>s are each independently a substituted or non-substituted monovalent hydrocarbon or an alkenyl group) and (F) an organosilicon compound having an SiH group and an alkoxy and/or oxirane group. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
