Description
本発明に従う方法では、中断された反応物質供給が最先端の技術のように再開信号から行われ、燃料電池電圧が規定され、これはトランスデューサーによって適宜調整される。反応物質が供給される電気的に無負荷の燃料電池がすべての場合に規定の燃料電池電圧を超えるように規定の燃料電池電圧が規定されることが、本発明に従って提供される。また、規定の燃料電池電圧を維持するために必要なトランスデューサーの電流が計測され、その後、通常動作がその実施のために必要な規定の電流の時点でリリースされることも規定される。本発明に従う方法はまた、該電圧が、反応物質を提供された正常に機能する燃料電池のアイドル電圧未満であるように規定の燃料電池電圧の上限を使用する。特に規定の燃料電池電圧は、それらの触媒での重大な腐食効果を燃料電池の寿命の見地から避けられるように、予め設定され得る。該規定の閾値未満の燃料電池によって伝達された電圧を維持するように、燃料電池の反応物質供給の開始時点で、電流は燃料電池からトランスデューサーを介して引き出される。トランスデューサーで引き出され測定された電流が、規定の電圧以下の電圧で現在の電流を維持するために必要な予め設定された値に達するとすぐに、燃料電池は再びストレスに耐えることができるはずである。一旦該規定の電流が達せられると、特に開始後の燃料電池の早い負荷による電圧の遮断などの、動作に関しての欠点を心配することなしに燃料電池の通常動作がリリースされる。
