摘要： Provided is a sealingmember to be used for sealing a constituent member of a fuel cell, the sealing member including a cross-linked product of a rubber composition, in which the rubber composition contains the following components (A) and (B). With this, rubber elasticity is maintained without being lost even under extremely low temperature conditions, and in the case where the sealing member is used in a fuel cell sealed body, an excellent sealing property is exhibited. (A) a rubber component including at least one of an ethylene-propylene rubber or ethylene-propylene-diene rubber having a ratio of ethylene-ethylene diad distribution of at most 29 mol%. (B) a cross-linking agent including an organic peroxide.

摘要： There is provided a rubber composition which does not foul molds, requires low production costs and is excellent in mass productivity, and has high adhesion reliability. The rubber composition according to the present invention is used in an adhesive layer 6 included in a fuel cell sealed body allowing a constituting member for a fuel cell 2, 3 or 5 and a rubber member for sealing 4a or 4b to be bonded together through the adhesive layer 6 or allowing the two rubber members 4a and 4a to be bonded together through the adhesive layer 6, and is any one of the following liquid rubber composition (±) and the following solvent-based rubber composition (²). (±) a liquid rubber composition containing (B) and (C) together with the following (A1). (²) a solvent-based rubber composition containing a solvent together with the following (A2), (B) and (C). (A1) a rubber component containing at least liquid rubber. (A2) at least one selected from the group consisting of EPM, EPDM, NBR and H-NBR. (B) a crosslinking agent composed of an organic peroxide. (C) at least one selected from the group consisting of resorcinol-based compounds, melamine-based compounds, aluminate-based coupling agents and silane coupling agents.
