Title (EN) HIGH TEMPERATURE ELECTROCHEMICAL CONVERTER FOR HYDROCARBON FUELS
(FR) CONVERTISSEUR ELECTROCHIMIQUE A HAUTE TEMPERATURE POUR CARBURANTS HYDROCARBONES
Abstract:
(EN) A sulfur-tolerant electrochemical converter having low internal resistance that is capable of directly processing hydrocarbon fuel having a sulfur component of up to about 50 ppm, and in excess of this amount, without suffering permanent structural damage or suffering a significant and/or permanent decrease in overall operating performance. The electrochemical converter is a high temperature fuel cell that has an operating temperature between about 600 °C and about 1200 °C and is capable of internally vaporizing and/or reforming the hydrocarbon fuel. One or more of the converter constituents, such as the interconnector, the contact surfaces of the interconnector, the fuel electrode, and the oxidizer electrode, is composed of a selected mixture containing chromium oxide and an alkaline metal oxide.
(FR) L'invention porte sur un convertisseur tolérant la présence de soufre, pourvu d'une résistance interne de faible valeur, capable de traiter directement un carburant hydrocarboné comportant du soufre comme composant, dans des quantités atteignant jusqu'à 50 p.p.m. et au-delà, sans subir de dommage de structure permanent ou une diminution importante et/ou permanente de ses capacités totales de fonctionnement. Ce convertisseur électrochimique est une cellule à haute température pour combustible, d'une température de fonctionnement comprise entre 600 et 1200 °C environ, capable de vaporiser intérieurement le carburant hydrocarboné et/ou de le reformer. Un mélange sélectionné contenant de l'oxyde de chrome ainsi qu'un oxyde de métal alcalin entre dans la composition d'un ou plusieurs constituants du convertisseur, dans celle de l'interconnecteur, de ses surfaces de contact ainsi que dans celle de l'électrode du carburant et de l'électrode de l'agent oxydant, notamment.
