In a method for operating a SOFC high-temperature fuel cell, wherein a hydrogen-containing fuel is converted internally in the fuel cell by an endothermic reaction at the anode thereof into a synthesis gas, which is converted by an exothermic reaction into electricity, fuel is supplied to the fuel cell, to cool the fuel cell, in an excess amount such that, with a predetermined average current density flow, the fuel utilization degree is below 40%, whereas the oxygen is supplied stoichiometrically corresponding to the amount of electricity generating requirements. No additional coolants are therefore reqired for the cooling of the fuel cell. |
