Abstract
(DE)
BZ-Stapel mit Flüssigkeitskühlung, insbesondere zur stationären Anwendung, wobei im Kühlsystem neuartige Dichtrahmen (1) verwendet werden, die den Zwischenraum zwischen benachbarten BZ-Einheiten (4) dicht abschliessen und die gleichzeitig Versorgungs- und Verteilungskanäle für das Kühlmittel integriert enthalten.
(EN)
The invention relates to a fuel cell stack with liquid cooling, especially for stationary use. The cooling system uses novel sealing frames (1) which tightly seal the intermediate space between adjacent fuel cell units (4) and which also contain integrated supply and distribution channels for the coolant.
(FR)
L'invention concerne un empilement de piles à combustible à refroidissement par liquide, destiné notamment à une utilisation fixe, selon lequel des cadres d'étanchéité d'un genre nouveau sont utilisés dans le système de refroidissement et ferment hermétiquement l'espace intermédiaire entre des unités adjacentes de piles à combustible et contiennent simultanément des canaux d'alimentation et de répartition pour l'agent réfrigérant.
