Description
−特に燃料電池付近で介入が必要である場合、それ自体の残存電圧が、人に対する危険性を有すること、
−依然として電池に存在するガスの長引く制御されない排気が、大気圧に対するガス回路内の圧力を低減し、燃料電池の要素の良好な機械的条件に有害な場合がある圧力差を生じさせる可能性があること。
−アノード側の燃料ガス給送回路と、
−回路を大気に開放することを可能にする手段を含むカソード側の酸素給送回路と、
を含み、この停止方法は、
・酸素の供給が中断される初期段階と、
・持続電流が燃料電池から引き出される消費段階と、
・酸素給送回路が大気に開放される中性化段階と、
・燃料ガスの供給が中断される最終段階と、
を含む。
本説明の残りの部分は、添付図面を参照して本発明の態様の全てを明らかにする。
燃料電池1は、制御ユニット15によって制御される。この制御ユニット15は、水素回路内(センサ111)及び酸素回路内(センサ121)の圧力センサから、電力線10の電圧測定装置13から、及び停止方法のための開始要素16(例えば、接触キー)から情報を受信し、かつ制御ユニット15は、様々なバルブ(110、120、122)の作動を制御する。
水素回路は、決して大気に開放されず、アノード側のガス回路にまだ水素がいくらか残っているとしても、電気化学反応は、アノード側の燃料ガス回路を大気に開放する段階なしに実質的に停止されることが見出されている。本発明によって提案される停止方法の別の利点は、停止された後に、燃料電池が迅速な再始動に好ましい構成のままであるということである。
