Abstract:
A method for operating a high-temperature solid oxide fuel cell including an anode and a cathode, said method comprising the steps:converting a hydrocarbon-containing fuel in the fuel cell internally, by an endothermic reaction directly at or in the anode, into a synthesis gas, and converting the synthesis gas in the fuel cell by an exothermic chemical reaction into electricity, wherein the fuel is supplied to the fuel cell at such an excess that the fuel utilization is below 40%, the temperature difference of the operating media between the entrance into, and the exit out of, the anode space as well as into, and respectively, out of, the cathode space is not more than 20Â° C., and, the oxygen is supplied to the fuel cell essentially stoichiometrically corresponding to the electric power generating requirement.
