Description
水素イオン(H+)は電解質膜を燃料極側から酸化剤極側へと透過し、酸化剤極に含まれる触媒(例えば主にプラチナ(Pt))により水素イオン(H+)は空気供給路により燃料電池の酸化剤極に供給された空気中の酸素(O2)と以下のように反応して水(H2O)となる。
電子(e-)がカソード電極とアノード電極とを結ぶ電線によりカソードからアノードに向かい移動することにより所定の電力を発生させる。
或いは、上述した目的を達成するために、この発明は:電解質膜と、アノード触媒を含み電解質膜の一方の側に配置され液体燃料が供給されるとともに前記アノード触媒によって促進される化学反応によって生じる気体が排出される燃料極と、カソード触媒を含み電解質膜の他方の側に配置され空気が供給される酸化剤極と、を含んでおり、電力を発生させる燃料電池と;燃料電池にかかる負荷を制御する負荷制御部と;を備えている燃料電池装置において、負荷制御部に、燃料電池が発生させる電力が所定の基準値よりも低下した場合及び所定の時間間隔の少なくともいずれか一方で、上記負荷を増加させ、そして、上記負荷の増加の開始から所定の時間の経過後に上記負荷の増加を停止させ、上記燃料電池は酸化剤極に空気を供給する為の空気供給路を含んでいて、上記空気供給路には供給空気量調整機構が設けられていて、供給空気量調整機構は、上記負荷制御部による上記負荷の増加にともない上記空気供給路を介した供給空気量の削減又は空気供給の停止を行なう、ことを特徴としている。
しかも前者の燃料電池装置においては、上記負荷制御部は、上記負荷を増加させる直前に、燃料極に供給される燃料の量を増加させるので、燃料不足による燃料極の触媒の破壊の発生の可能性を阻止する。
また、後者の燃料電池装置においては、上記燃料電池は酸化剤極に空気を供給する為の空気供給路を含んでいて、上記空気供給路には供給空気量調整機構が設けられていて、供給空気量調整機構は、上記負荷制御部による上記負荷の増加にともない上記空気供給路を介した供給空気量の削減又は空気供給の停止を行なう。これにより燃料電池の酸化剤極に酸素が不足した状態を容易に効率よく作り出すことが出来る。
水素イオン(H+)は電解質膜12aを燃料極12b側から酸化剤極12c側へと透過し、酸化剤極12cに含まれる触媒(例えばプラチナ(Pt))により水素イオン(H+)は空気供給路により酸化剤極12cに供給された空気中の酸素(O2)と以下のように反応して水(H2O)となる。
電子(e-)がアノードから外部に流出されることにより所定の電力を発生させる。
