Abstract

[OBJECT] In an SOFC cell comprising a Cr-containing alloy or the like and an air electrode bonded together, the invention is to provide a cell capable of effectively restricting occurrence of Cr poisoning of the air electrode and capable also of effectively restricting occurrence of oxidation deterioration due to Cr depletion in the alloy or the like. [SOLUTION] In a cell for a solid oxide fuel cell (SOFC) comprising a Cr (chrome)-containing alloy or oxide and an air electrode bonded together, wherein on the surface of the alloy or oxide, there is formed a coating layer containing a spinel oxide comprised of a first mono metal oxide and a second mono metal oxide, the first mono metal oxide having an equilibrium dissociated oxygen partial pressure at 750° C. ranging from 1.83×10to 3.44×10atm., the second mono metal oxide having a lower equilibrium dissociated oxygen partial pressure at 750° C. than the first mono metal oxide.
