Title
(EN) SEAL MEMBER FOR FUEL CELL AND FUEL CELL SEAL BODY USING SAME
(FR) ÉLÉMENT DE SCELLEMENT POUR PILE À COMBUSTIBLE ET CORPS DE SCELLEMENT POUR PILE À COMBUSTIBLE L'UTILISANT
(JA) 燃料電池用シール部材およびそれを用いた燃料電池シール体
Abstract
(EN)
This seal member comprises a cross-linked body of a rubber composition and is used for sealing members configuring a fuel cell, and the rubber composition contains the (A) and (B) mentioned below. As a result, rubber elasticity is maintained without loss of rubber elasticity under extremely low temperature conditions, and when used in a fuel cell sealing body, there are superior sealing properties. (A) A rubber component comprising ethylene-propylene rubber and/or ethylene-propylene-diene rubber of which the distribution of ethylene-ethylene diads is no greater than 29 mol%. (B) A cross-linking agent comprising an organic peroxide
(FR)
Cet élément de scellement comprend un corps réticulé d'une composition de caoutchouc et est utilisé pour sceller des éléments configurant une pile à combustible, et la composition de caoutchouc contient les (A) et (B) mentionnés ci-après. Comme résultat, une élasticité de caoutchouc est maintenue sans perte d'élasticité de caoutchouc dans des conditions de température extrêmement basse, et lorsqu'il est utilisé dans un corps de scellement de pile à combustible, il y a des propriétés de scellement supérieures. (A) Un composant de caoutchouc comprenant un caoutchouc éthylène-propylène et/ou un caoutchouc éthylène-propylène-diène dont la distribution des diades éthylène-éthylène n'est pas supérieure à 29 % en moles. (B) Un agent de réticulation comprenant un peroxyde organique.
(JA)
 燃料電池の構成部材をシールするために用いられる、ゴム組成物の架橋体からなるシール部材であって、上記ゴム組成物が下記の(A)および(B)を含有する。このため、極低温条件下においてもゴム弾性が失われることがなくゴム弾性が維持され、燃料電池シール体に使用した場合、優れたシール性を備えるようになる。 (A)エチレン-エチレンの2連子分布が29モル%以下である、エチレン-プロピレンゴムおよびエチレン-プロピレン-ジエンゴムの少なくとも一方からなるゴム成分。 (B)有機過酸化物からなる架橋剤。
