Title
(EN) APPARATUS FOR GENERATING A GAS WHICH MAY BE USED FOR STARTUP AND SHUTDOWN OF A FUEL CELL
(FR) APPAREIL PERMETTANT DE GÉNÉRER UN GAZ QUI PEUT ÊTRE UTILISÉ POUR LE DÉMARRAGE ET L'ARRÊT D'UNE PILE À COMBUSTIBLE
Abstract
(EN)
The present invention provides a gas generator that may be used for startup and shutdown of a fuel cell. In one non-limiting embodiment, the gas generator may include a nitrogen generator structured to receive air, extract oxygen (O2) from the air and discharge the balance in the form of a nitrogen-rich gas; a merging chamber structured to receive a hydrocarbon fuel and the nitrogen-rich gas and to discharge a feed mixture containing both the hydrocarbon fuel and the nitrogen-rich gas; and a catalytic reactor structured to receive the feed mixture and to catalytically convert the feed mixture into a reducing gas.
(FR)
La présente invention a trait à un générateur de gaz qui peut être utilisé pour le démarrage et l'arrêt d'une pile à combustible. Selon un mode de réalisation non limitatif, le générateur de gaz peut inclure un générateur d'azote structuré pour recevoir de l'air, extraire l'oxygène (O2) de l'air et décharger le reste sous la forme d'un gaz riche en azote; une chambre de fusion structurée pour recevoir un hydrocarbure et le gaz riche en azote et pour décharger un mélange d'alimentation contenant à la fois l'hydrocarbure et le gaz riche en azote; et un réacteur catalytique structuré pour recevoir le mélange d'alimentation et pour convertir de façon catalytique le mélange d'alimentation en un gaz réducteur.
