Abstract

　本発明の目的は、アルコール燃料を気化供給する固体高分子型燃料電池において、優れた発電特性及び保管特性を実現できる燃料電池を提供することである。燃料極８に相対する燃料供給部１が、高濃度燃料槽３と、水分を貯蔵する水燃料槽４とによって構成されており、燃料極８と燃料槽３、４の間に細孔板（３ｄ、４ｄ）及び気液分離性を有する多孔質体（気化供給部３ｃ、４ｃ）からなる燃料気化供給層を具備しており、さらに高濃度燃料槽３側の燃料極横にＣＯ２ガス排出口６を設けたことを特徴とする固体高分子型燃料電池を提供する。このように簡易な構造によって、発電時において燃料槽で必要なアルコール及び水を確保でき、安定した発電特性が得られる。さらに、保管時には水燃料槽４のみを開放状態にして発電部２を加湿することで優れた保管特性及び起動特性を実現する。
