Title
(DE) VERFAHREN ZUR ÜBERPRÜFUNG MINDESTENS EINES SENSORS INNERHALB DES ANODENPFADES EINES BRENNSTOFFZELLENSYSTEMS
(EN) METHOD FOR CHECKING AT LEAST ONE SENSOR WITHIN THE ANODE PATH OF A FUEL CELL SYSTEM
(FR) PROCÉDÉ POUR CONTRÔLER AU MOINS UN CAPTEUR À L'INTÉRIEUR DU CHEMIN ANODIQUE D'UN SYSTÈME DE PILE À COMBUSTIBLE
Abstract
(DE) Verfahren zur Überprüfung von mindestens zwei Sensoren innerhalb eines Anodenpfades (4) eines Brennstoffzellensystems (1), umfassend die Schritte eines Herunterfahrens des Brennstoffzellensystems (1); eines Schließens des Absperrventils (32) und des Purge-Ventils (41); eines Öffnens eines internen Ventils (34); eines Erfassens der Druckwerte von mindestens zwei Sensoren (50, 51, 52, 53, 54) innerhalb des Anodenpfades; eines Überprüfens, ob sich die Druckwerte der mindestens zwei Sensoren (50, 51, 52, 53, 54) unterscheiden.
(EN) The invention relates to a method for checking at least two sensors within an anode path (4) of a fuel cell system (1), having the steps of shutting down the fuel cell system (1); closing the shut-off valve (32) and the purge valve (41); opening an internal valve (34); detecting the pressure values of at least two sensors (50, 51, 52, 53, 54) within the anode path; and checking whether the pressure values of the at least two sensors (50, 51, 52, 53, 54) differ.
(FR) L'invention concerne un procédé pour contrôler au moins deux capteurs à l'intérieur d'un chemin anodique (4) d’un système de pile à combustible (1), comprenant les étapes consistant à arrêter le système de pile à combustible (1) ; fermer la soupape d'arrêt (32) et la soupape de purge (41) ; ouvrir une soupape interne (34) ; déterminer les valeurs de pression d'au moins deux capteurs (50, 51, 52, 53, 54) à l'intérieur du chemin anodique ; contrôler si les valeurs de pression desdits au moins deux capteurs (50, 51, 52, 53, 54) diffèrent.
