Abstract

　本発明は、発電に伴う液体燃料の減少によって燃料収容部の内圧が低下することを抑制し、ポンプの実質的な送液能力を確保することで、燃料電池セルに対する燃料供給の安定化、および発電反応の効率化を図り、出力特性に優れる燃料電池を提供することを目的とする。 本発明は、燃料電池１は、膜電極接合体２と、燃料供給機構３と、内圧調整機構４とを有している。膜電極接合体２は、燃料極１３と、空気極１６と、これらに挟持された電解質膜１７とを有している。燃料供給機構３は、膜電極接合体２の燃料極１３側に配置される燃料分配機構５と、燃料収容部６と、これらを繋ぐ流路７と、この流路７に設けられたポンプ８とを有している。内圧調整機構４は、燃料収容部６の内圧が低下したときに外気を導入するものであり、燃料供給機構３においてポンプ８よりも燃料収容部６側に設けられている。
