Abstract
A method of operating a solid oxide cell system comprises generating an electrochemical conversion from one of: (i) water steam H2O(g); and (ii) a mixture comprising water steam H2O(g) and carbon dioxide CO2. A quantity of at least one other substance is added into the one of the water steam H2O(g) and the mixture comprising water steam H2O(g) and carbon dioxide CO2. The at least one other substance comprises a hydrocarbon CmHn. The quantity of the at least one other substance is converted into a syngas CO+H2. An endothermic reforming of the mixed-in hydrocarbons occurs by coupling-in waste heat from the electrochemical conversion. The additional quantity of the at least one substance is added compensate for effects of a degradation of the solid oxide cells of the solid oxide cell system. A total quantity of the hydrogen H2 generated by the solid oxide cell system is kept constant.
