Description
上記のような燃料電池においては燃料ガス、酸化剤ガスおよび冷媒を、それぞれ独立したガス通路及び冷媒通路に流通させる必要があることから、これら通路をシールによって隔絶している。シールする部位としては、燃料電池スタックの構造により若干異なるが、例えば燃料電池スタックを貫通するガス通路の連通口の周囲、電極構造体の周縁部、セパレータの表面に設けられた冷媒通路の周囲、セパレータ表面の周縁部等が挙げられる。
そのためガスケット材料には低温性を改良したフッ素ゴムを単独で使用したりエチレンプロピレン系ゴムあるいはパーフロロアルキルエーテル系フッ素ゴムをブレンドしたものが用いられつつある。
本発明の接着剤組成物は、従来の接着剤より耐酸性を向上させ、安定した接着性を得る接着剤組成物を提供することを課題とするものである。
よって、請求項1における接着剤組成物を燃料電池用に用いられるガスケットの接着剤として用いれば、酸性化した生成水に対する耐性をもつため、長期にわたり安定したガスケット接着をなすことができ、ガスケットとしてのシール機能を長期にわたり発揮させることができる。
本発明で使用される接着剤のエポキシ樹脂は、主剤として末端に反応性のエポキシ基をもつ熱硬化型のエポキシ樹脂でビスフェノールFとエピクロルヒドリンとの縮合反応により製造されたビスフェノールF型エポキシ樹脂である。硬化剤である変性ポリアミドアミンは、エポキシ化合物、アクリル酸、メタクリル酸、メタクリロニトリル、フェノール、カルボン酸、アクリロニトリル、カルボン酸ハライド、アミド、有機ハロゲン化物等により変性され、例としてゴム変性ポリアミドアミン、エポキシ変性ポリアミドアミン、変性脂環式ポリアミドアミン、変性脂肪族ポリアミドアミン、イミダゾリン環含有変性ポリアミドアミンなどがあげられる。
これらの主剤と硬化剤の配合比率は主剤及び硬化剤が30対70〜95対5、好ましくは90対10で配合される。また必要に応じて主剤、硬化剤が溶解する有機溶媒等に希釈して用いてもよい。
このように配合されたエポキシ樹脂接着剤はカーボン、メタル等で成形されたセパレータに刷毛、スプレー、浸せき等にて塗布され、常温では塗布後1分〜24時間、好ましくは40分〜6時間乾燥する。この場合時間短縮の為、必要に応じて例えば50℃〜150℃で10分間程度乾燥させてもよい。
オープンロールにて混練りし、170℃、3分でプレス加硫、200℃、4時間でオーブンによる2次加硫を行い、厚さ1mmのゴムシートを作製した。
Claims (2)
- ゴム組成物よりなるガスケット材料を燃料電池用のセパレータに接着するために用いられる接着剤組成物であって、
主剤としてビスフェノールF型のエポキシ樹脂を用い、硬化剤として変性脂肪族ポリアミドアミンを用い、前記ゴム組成物は、下記一般式(化1)で示されるフッ素ゴム単独、あるいは前記フッ素ゴムをベースにエチレンプロプレン系ゴムあるいはパーフロロアルキルエーテル系フッ素ゴムをブレンドしてなるものを用いることを特徴とする接着剤組成物。
- 請求項1において、
前記主剤と前記硬化剤の配合比率は前記主剤及び前記硬化剤が30対70〜95対5でブレンドされたことを特徴とする接着剤組成物。
