    摘要： A fuel cell system is provided. The fuel cell system may be a segmented-in-series, solid-oxide fuel cell system. The system may comprise a fuel cell tube and a secondary interconnect. The fuel cell tube may comprise a substrate, a fuel channel, a first and second electrochemical active fuel cell, a primary interconnect, and an electrochemically inactive cell. The substrate may have a major surface. The fuel channel may be separated from the major surface by the substrate. The first and second electrochemically active fuel cells may be disposed on the major surface, and may comprise and anode, a cathode, and an electrolyte disposed between the anode and the cathode. The primary interconnect may electrically couple the anode of the first electrochemically active fuel cell to the cathode of a second electrochemically active fuel cell. The electrochemically inactive fuel cell may be disposed on the major surface and comprise a conductive layer electrically coupled to the second electrochemically active fuel cell. The secondary interconnect may be coupled to the conductive layer of the electrochemically inactive cell. The electrochemically inactive cell is configured to inhibit the migration of hydrogen from said fuel channel to the secondary interconnect.

    摘要： A fuel cell system is provided. The fuel cell system may be a segmented-in-series, solid-oxide fuel cell system. The fuel cell system may comprise a first and second fuel cell tube and a secondary interconnect. Each of the fuel cell tubes may comprise a substrate having a first and second end and a pair of generally planar opposing major surfaces extending between the ends, a plurality of fuel cells disposed on one of said major surfaces, wherein the fuel cells are electrically coupled in series, a first sheet conductor providing an electrical path from a location on one of the major surfaces to a location on the other of the major surfaces proximate the first end of the substrate, the first sheet conductor being electrically coupled to said plurality of fuel cells, and a second sheet conductor providing an electrical path from a location on one of the major surfaces to a location on the other of the major surfaces proximate the second end of said substrate, the second sheet conductor being electrically coupled to said plurality of fuel cells. The secondary interconnect may provide an electrical path between the first and second fuel cell tubes. The first fuel cell tube may be positioned with a major surface thereof being spaced from and parallel to a major surface of the second fuel cell tube, the secondary interconnect being electrically coupled to said first sheet conductor of each of said first and second fuel cell tubes.

    摘要： In accordance with some embodiments of the present disclosure, a fuel cell system is provided. The fuel cell system may comprise a plurality of stacked fuel cell tubes and a secondary interconnect. Each tube may comprise a substrate, a plurality of fuel cells, a first sheet conductor, and a second sheet conductor. The substrate may have a pair of opposing major surfaces and define a plurality of parallel channels between the major surfaces extending from a first end to a second end of said tube. The plurality of fuel cells may be disposed on one of said major surfaces, the fuel cells being electrically coupled in series to one another. The first sheet conductor may be located proximate the first end of the tube, the first sheet conductor providing an electrical path from a location on one of the major surfaces to a location on the other of the major surfaces. The second sheet conductor may be located proximate the second end of the tube, the second sheet conductor providing an electrical path from a location on one of the major surfaces to a location on the other of the major surfaces. The secondary interconnect may electrically couple the first sheet conductors on adjacent fuel cell tubes thereby electrically coupling the fuel cells disposed on one fuel cell tube to the fuel cells disposed on an adjacent fuel cell tube.

    摘要： A fuel cell system and corresponding methods are provided. The fuel cell system includes a fuel cell stack configured for in-block reforming, as well as a pre-reformer. The fuel cell stack may include a plurality of fuel cells. The fuel cell stack may also include a fuel supply manifold, a fuel exhaust manifold, an oxidant supply manifold, and an oxidant exhaust manifold. The fuel supply manifold may be configured to receive fuel, and to supply the fuel to the fuel cell stack for in-block reforming. The fuel exhaust manifold may be configured to expel fuel exhaust from the fuel cell stack. The oxidant supply manifold may be configured to receive an oxidant and to supply the oxidant to the fuel cell stack for in-block reforming. The oxidant exhaust manifold may be configured to expel oxidant exhaust from the fuel cell stack.

    摘要： In accordance with some embodiments, the present disclosure is directed to systems having a fuel cell and a turbine generator, each capable of providing electrical power to a utility grid, and methods for operating the same. The system may have a main AC bus which is coupleable to the utility grid. The fuel cell may be coupled to main AC bus through an inverter. The turbine generator may be coupled to the main AC bus through a series of inverters, one of which may include the inverter by which the fuel cell is connected to the main AC bus. One or more load banks may be provided to provide a load for electrical power generated from the fuel cell, turbine generator, or both in case the system is disconnected from the utility grid. Further support and backup systems may be provided.
