Abstract[German]
Ein Verfahren zum Entfernen von Brennstoff aus einer Brennstoffzelle (6) umfasst: A) fluidisches Verbinden einer Inertgasquelle (12) mit der Brennstoffzelle (6); B) Zuführen eines Inertgases (13) aus der Inertgasquelle (12) in die Brennstoffzelle (6); und C) Abführen eines Gasgemisches (19), das Inertgas (13) und Brennstoffgas (11) enthält, aus der Brennstoffzelle (6). Dabei werden die Schritte B) und C) durchgeführt und/oder wiederholt werden, bis die Konzentration von des Brennstoffgases (11) in der Brennstoffzelle (6) einen vorgegebenen Brennstoffgaskonzentrationsgrenzwert unterschreitet.[English]
The invention relates to a method for removing fuel from a fuel cell (6), comprising: A) fluidically connecting an inert gas source (12) to the fuel cell (6); B) feeding an inert gas (13) from the inert gas source (12) into the fuel cell (6); and C) discharging a gas mixture (19) containing inert gas (13) and fuel gas (11) from the fuel cell (6). Steps B) and C) are carried out and/or repeated until the concentration of the fuel gas (11) in the fuel cell (6) falls below a specified fuel gas concentration limit value.[French]
L'invention concerne un procédé d'élimination de combustible d'une pile à combustible (6), consistant à : A) raccorder de manière fluidique une source de gaz inerte (12) à la pile à combustible (6) ; B) alimenter la pile à combustible (6) en gaz inerte (13) provenant de la source de gaz inerte (12) ; et C) évacuer un mélange gazeux (19) contenant du gaz inerte (13) et du gaz combustible (11) de la pile à combustible (6). Les étapes B) et C) sont effectuées et/ou répétées jusqu'à ce que la concentration en gaz combustible (11) dans la pile à combustible (6) tombe au-dessous d'une valeur limite spécifiée pour la concentration en gaz combustible.
