Title: (EN) HIGH TEMPERATURE ELECTROCHEMICAL CONVERTER FOR HYDROCARBON FUELS
(FR) CONVERTISSEUR ELECTROCHIMIQUE A HAUTE TEMPERATURE POUR CARBURANTS HYDROCARBONES
Abstract: front page image
(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.
