Patent ID: 7989113

Claim:
A solid oxide fuel cell module, comprising: a plurality of cells, each cell comprising a fuel electrode, an air electrode and an electrolyte provided between the fuel electrode and the air electrode; an interconnector for electrically connecting the air electrode and the fuel electrode of adjacent cells in series; a substrate having an internal fuel flow path for a fuel to flow through and an insulating face in contact with the plurality of cells; a cell group is formed of a plurality of cells having an identical area and a plurality of the cell groups are formed on the substrate; individual cells not belonging to any cell group are also formed on the substrate; wherein the cell groups and the individual cells are disposed such that the areas of the individual cells and the respective cells of the cell groups sequentially increase along a direction of the fuel flow, and a constituent material of each interconnector comprises silver and each interconnector is covered with glass, a constituent material of each interconnector comprises an oxide expressed by chemical formula (Ln, A) CrO 3 , where Ln refers to lanthanoids and A refers to Ba, Ca, Mg or Sr or a constituent material of each interconnector comprises an oxide material containing Ti.
