| 摘要 |
An object of the present invention is to provide an interconnector material which is chemically stable in both oxidation atmospheres and reduction atmospheres, has a high electron conductivity (electric conductivity), a low ionic conductivity, and a composition not containing Cr, and enables a reduction in sintering temperature. The interconnector material is arranged between a plurality of cells each composed of an anode layer, a solid electrolyte layer, and a cathode layer stacked sequentially, and electrically connects the plurality of cells to each other in series in a solid electrolyte fuel cell, wherein a dominant component of the material is a ceramic composition represented by the composition formula La(Fe 1-x Al x )O 3 in which x represents a molar ratio satisfying 0 < x < 0.5. |
