Abstract[German]
Die vorliegende Erfindung betrifft ein Verfahren zur Erkennung eines elektrischen Kurzschlusses an einem Brennstoffzellenstapel (110) eines Brennstoffzellensystems (120), wobei die folgenden Schritte vorgesehen sind: - Überwachen wenigstens eines Gasdrucks (GD) im Brennstoffzellensystem (100), - Vergleich des überwachten Gasdrucks (GD) mit wenigstens einem Druckgrenzwert (DGW) auf einen Druckabfall, - Erzeugen eines Kurzschluss-Fehlersignals (KFS), wenn der überwachte Gasdruck (GD) den wenigstens einen Druckgrenzwert (DGW) unterschreitet.[English]
The present invention relates to a method for detecting an electrical short circuit in a fuel cell stack (110) of a fuel cell system (120), the following steps being provided: - monitoring at least one gas pressure (GD) in the fuel cell system (100), - comparing the monitored gas pressure (GD) with at least one pressure threshold (DGW) to detect a pressure drop, - generating a short-circuit fault signal (KFS) if the monitored gas pressure (GD) falls below the at least one pressure threshold (DGW).[French]
La présente invention concerne un procédé de détection d'un court-circuit électrique dans un empilement de piles à combustible (110) d'un système de pile à combustible (120), les étapes suivantes étant proposées : - surveiller au moins une pression de gaz (GD) dans le système de pile à combustible (100), - comparer la pression de gaz surveillée (GD) à au moins un seuil de pression (DGW) pour détecter une chute de pression, - générer un signal de défaut de court-circuit (KFS) si la pression de gaz surveillée (GD) chute sous le ou les seuils de pression (DGW).
