Abstract
(DE)
Ein Brennstoffzellensystem umfasst wenigsten eine Brennstoffzelle (4), einen elektrischen Zwischenspeicher (7), der mit gemeinsamen Versorgungsanschlüssen (8) für einen elektrischen Verbraucher (9) verbunden ist, wenigstens einen Sensor (10) zum Erfassen eines Betriebsparameters der wenigstens einen 10 Brennstoffzelle, einen Schalter (6) zum elektrischen Verbinden und/oder Trennen der Brennstoffzelle (4) von dem Zwischenspeicher (7) und den Versorgungsanschlüssen (8) sowie eine Steuerschaltung (11) zum Öffnen und Schließen des Schalters (6) in Abhängigkeit von dem erfassten Betriebsparameter.
(EN)
The invention relates to a fuel cell system comprising at least one fuel cell (4), an electric intermediate accumulator (7), which is connected to common supply terminals (8) for an electric consumer (9), at least one sensor (10) for detecting an operating parameter of the fuel cell(s), a switch (6) for electrically connecting and/or disconnecting the fuel cell (4) to and from the intermediate accumulator (7) and the supply terminals (8), in addition to a control circuit (11) for opening and closing the switch (6) in accordance with the detected operating parameter.
(FR)
L'invention concerne un système de pile à combustible qui comprend au moins une pile à combustible (4), un accumulateur électrique intermédiaire (7) relié à des bornes d'alimentation communes (8) pour un consommateur électrique (9), au moins un capteur (10) servant à détecter un paramètre de fonctionnement de la pile à combustible, un commutateur (6) servant à relier électriquement la pile à combustible (4) à l'accumulateur intermédiaire (7) et aux bornes d'alimentation (8) ou à la séparer électriquement de ces derniers, ainsi qu'un circuit de commande (11) servant à ouvrir et à fermer le commutateur (6) en fonction du paramètre de fonctionnement détecté.
