INTER-CONNECTOR AND SOLID OXIDE FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide a solid oxide fuel cell in which deterioration by oxidation of an interconnector can be suppressed by using a protection film made of a material with high conductivity even in a high temperature state such as power generation operation of the solid oxide fuel cell.

SOLUTION: A protection film 108 made of lanthanum nickel ferrite is coated at least on the surface on air electrode side of the air electrode side interconnector 107. In other words, the surface which is exposed on an oxidant gas on at least the air electrode side of the air electrode side interconnector 107 is covered with the protection film 108 made of lanthanum nickel ferrite (LNF).
