Description
(OCV)を示し、発電中よりも電圧が高くなる。この状態は電池内の触媒や電解質の劣化を促進させるので、長時間放置させるのは好ましくない。よって電池電圧を低下させる方法として、水素ラインに空気を導入して、水素極の電位を空気極の電位と同程度まで上昇させ、電池電圧としてはゼロに近づける方法がある。この場合、OCV状態による触媒や電解質の劣化はほとんど生じない。
実施例のシステム構成図を図1に示す。パーフオロカーボンスルホン酸系の電解質膜と、白金粒子をカーボン担体に担持させた触媒を主成分とする電極とを一体化した電極電解質膜を中心として、その表裏面にポリテトラフルオロエチレン(PTFE)を表面に分散させ撥水性を制御したカーボンペーパーであるカソード拡散層,アノード拡散層を配置し、さらに金属セパレータをその両側に配置して、発電セルの基本構成と成した。本発電セルを120セルおよび冷却水を流通させ電池温度を下げるための冷却セルを60セル組み合わせることにより、燃料電池スタック1を作製した。
