Title (EN) SUBDIVIDED COOLING CIRCUIT FOR A FUEL CELL SYSTEM
(FR) SOUS-SYSTEME DE REFROIDISSEMENT POUR SYSTEME DE PILE A COMBUSTIBLE ELECTROCHIMIQUE
Abstract: front page image
(EN)A method for operating a cooling subsystem of an electrochemical fuel cell system during startup is disclosed. The method comprises directing a startup coolant having a low heat capacity through an electrochemical fuel cell stack of the fuel cell system, and directing a standard coolant having a higher heat capacity through the fuel cell stack when the temperature of either the fuell cell stack or the startup coolant reaches a first predetermined temperature. The startup coolant can be a gas or a fluorocarbon, whereas the standard coolant comprises a liquid fluid such as a mixture of water and glycol.
(FR)L'invention concerne un procédé permettant de faire fonctionner un sous-système de système de pile à combustible électrochimique pendant un démarrage. Ledit procédé consiste à diriger un réfrigérant de démarrage à travers un empilement du système de pile à combustible, et à diriger un réfrigérant normalisé à travers l'empilement de pile à combustible lorsque la température de cet empilement ou du réfrigérant de démarrage atteint un premier niveau prédéterminé, la capacité de chauffage du réfrigérant de démarrage étant différente de celle de la capacité de chauffage du réfrigérant normalisé. L'invention concerne également des sous-systèmes de refroidissement.
