Definitions

  • Hydrogen-rich fuel gas can be produced by steam reforming raw fuel.
  • fuel gas is generated by steam reforming, the fuel gas contains steam.
  • connecting members 18 are interposed between adjacent cells 1 among the plurality of cells 1.
  • the connecting member 18 electrically connects the fuel electrode 5 of one adjacent cell 1 and the air electrode 8 of the other cell 1 in series. More specifically, the connecting member 18 connects the interconnector 4, which is electrically connected to the fuel electrode 5 of one adjacent cell 1, and the air electrode 8 of the other cell 1.
  • the second region 7B may have a higher content of the second element than the first region 7A.
  • the content rates of the first element and the second element can be confirmed by elemental analysis using EPMA, EDS, etc., for example.
  • the cross section of the element portion 3 in the stacking direction is mirror-polished, the intermediate layer 7 is divided into two equal parts in the thickness direction, and the porosity is calculated by, for example, image analysis.
  • the side with a smaller porosity is defined as a first part 7A
  • the side with a larger porosity is defined as a second part 7B.
  • the reformer 102 generates fuel gas by reforming raw fuel such as natural gas or kerosene, and supplies the fuel gas to the cell 1.
  • Raw fuel is supplied to the reformer 102 through a raw fuel supply pipe 103.
  • the reformer 102 may include a vaporizing section 102a that vaporizes water, and a reforming section 102b.
  • the reforming section 102b includes a reforming catalyst (not shown), and reformes the raw fuel into fuel gas.
  • Such a reformer 102 can perform steam reforming, which is a highly efficient reforming reaction.
  • the intermediate layer 7 contains one or more elements (first element) selected from Cu, Na, and V, and Ce (second element).
  • the intermediate layer 7 may contain one or more first elements alone.
