Description
−アノード側に設けられた燃料ガス回路と、
−カソード側に設けられた純粋酸素回路とを有する、方法において、
・酸素ガス供給を中断する初期ステップと、
・純粋酸素回路中の圧力が水蒸気圧に達するまでホールド電流を燃料電池から引き出す電力消費ステップとを有することを特徴とする方法を提案する。
−除去されるべき水は、主としてカソード側に存在し、したがって、最小限の圧力により水の蒸発を保証するために酸素を全て消費することが好ましい。
−以下の3つの条件の組合せ、即ち、1)アノード側における水素の供給不足又は不存在、2)カソード側における酸素の存在、及び3)電流の維持の組合せは、劣化メカニズムの誘発、特に一般に触媒の支持体として用いられる炭素の迅速な腐食の原因である。
