  • Sulfur management and utilization in molten metal anode solid oxide fuel cells
    Patent number: 9685675
    Abstract: Embodiments of a molten metal anode solid oxide fuel cell (MMA-SOFC) system comprise a first MMA-SOFC and a second MMA-SOFC, a fuel contactor integral with the first MMA-SOFC or in fluid communication with the first MMA-SOFC, a molten metal conduit configured to deliver molten metal from a first molten metal anode to a second molten metal anode, and one or more external electric circuits, wherein a first molten metal anode is configured to oxidize molten metal to produce metal oxides and electrons, the fuel contactor is configured to reduce the metal oxides and produce metals and metal sulfides in the molten metal upon reaction with sulfur-containing fuel. The second molten metal anode is configured to oxidize the metal sulfides in the metal sulfides-containing molten metal to produce metals and electrons, and the external electric circuits are configured to generate power from the electrons produced in the first and second MMA-SOFCs.
