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： A fuel cell tube comprises a substrate having a tube interconnect region and a fuel cell region, a plurality of fuel cells disposed on the fuel cell region, and a plurality of primary interconnects formed from an electrically conducting primary interconnect material forming electrically conducting paths between adjacent fuel cells to thereby electrically connect the fuel cells in series. The primary interconnect material extends from the fuel cell region into the tube interconnect region forming an electrically conducting path between the tube interconnect region and the plurality of fuel cells.

摘要： Various embodiments of the present disclosure provide a fuel cell tube including one or more laterally segmented fuel cells each including multiple fuel cell portions that are electrically isolated from one another. When assembled into a fuel cell stack, tube interconnects electrically connect adjacent fuel cell tubes via their respective laterally segmented fuel cells. The use of laterally segmented fuel cells to effect the fuel cell tube-to-fuel cell tube electrical connection enables more accurate testing of the electrical connection between adjacent fuel cell tubes.
