  • Publication number: 20150140459
    Abstract: The cooling capacity of a first heat exchanger for cooling a reformed gas introduced into an inlet of a circulation pump is increased as an output of a fuel cell increases. With this configuration, an inlet temperature of the circulation pump is relatively high during low power generation and decreases as the generation power increases, and a volumetric flow rate during high power generation in which a large amount of reformed gas is required can be decreased relatively. As the result, a dynamic range required for the circulation pump can be made small. Furthermore, water condensation in the inlet of the circulation pump can be prevented during low power generation.

  • Publication number: 20140162154
    Abstract: A thermally integrated system for producing electricity from a feedstock fuel is disclosed. The system utilizes a reformer that includes a plasma zone to receive a pre-heated mixture of reactants and ionize the reactants by applying an electrical potential thereto. A first thermally conductive surface surrounds the plasma zone and is configured to transfer heat from an external heat source into the plasma zone. The reformer further includes a reaction zone to chemically transform the ionized reactants into synthesis gas comprising hydrogen and carbon monoxide. A second thermally conductive surface surrounds the reaction zone and is configured to transfer heat from the external heat source into the reaction zone. The first thermally conductive surface and second thermally conductive surface are both directly exposed to the external heat source. A corresponding method and apparatus are also disclosed herein.

  • Publication number: 20140030616
    Abstract: A solid oxide fuel cell system has a carbon monoxide generator using ultraclean coal or graphite, which includes a carbon supply unit, a carbon dioxide supply unit, a carbon monoxide generating unit, and a fuel cell unit. The carbon monoxide generating unit supplies CO to the anode of the fuel cell unit, and CO2 discharged from the fuel cell unit is recycled to the carbon dioxide supply unit. Because ultraclean coal or graphite is used, a separate reformer does not need to be used, and thus energy can be produced with high efficiency even at low costs. Because CO2 discharged from the solid oxide fuel cell, which uses carbon monoxide as a fuel, after a fuel cell reaction, is reused as reactant gas, carbon dioxide is not emitted into the atmosphere. Gasification can be smoothly achieved by the carbon monoxide generating unit including heating powder or a heating reaction chamber.
