Description
前記予備成形体14が、膨張黒鉛に繊維質充填材が加えられて成る原料を用いての抄造によって得られる第1シート14Aの一対の間に、黒鉛に熱硬化性樹脂を塗して成る第2シート14Bが介装されて成るサンドイッチ構造に構成されていることを特徴とするものである。
まず最初に、本発明のセパレータを備えた固体高分子電解質型燃料電池の構成及び動作について、図1〜図3を参照して簡単に説明する。固体高分子電解質型燃料電池Eは、例えばフッ素系樹脂より形成されたイオン交換膜である電解質膜1と、炭素繊維糸で織成したカーボンクロスやカーボンペーパーあるいはカーボンフェルトにより形成され、上記電解質膜1を両側から挟みサンドイッチ構造をなすガス拡散電極となるアノード2及びカソード3と、そのサンドイッチ構造をさらに両側から挟むセパレータ4,4とから構成される単セル5の複数組を積層し、その両端に図示省略した集電板を配置したスタック構造に構成されている。
