SELF-SUSTAINABLE SOLID OXIDE FUEL CELL SYSTEM AND METHOD FOR POWERING A GAS WELL

摘要

Embodiments of a self-sustainable solid oxide fuel cell (SOFC) system for powering a gas well comprise a first SOFC comprising a first cathode, a first anode, and a first solid electrolyte; a second SOFC comprising a second cathode, a second anode, and a second solid electrolyte; SO2 removal equipment; a combustion circuit comprising a combustor and a circulating heat carrier in thermal connection with the combustor, the first SOFC, and the second SOFC; and one or more external electric circuits. The first anode comprises a first oxidation region configured to produce SO2 and electrons. The second anode comprises a second oxidation region configured to electrochemically oxidize CH4 to produce syngas and electrons and electrochemically oxidize H2 to produce H2O and electrons. The external electric circuits are configured to generate power from the electrons produced in both the first SOFC and the second SOFC.
