Abstract:
1. A method for manufacturing a film formed article, wherein an interconnector film made of a lanthanum chromite-based perovskite oxide which includes calcium (Ca) in its composition is formed over a fuel electrode of a solid oxide fuel cell, the fuel electrode having a composition forming solid solution with calcium (Ca), the method comprising: forming as film a non-electrolyte intermediate layer including as a main ingredient a single phase perovskite oxide and having electronic conduction properties on the fuel electrode, the perovskite oxide is represented by a chemical formula: wherein A is one or more elements selected from a group consisting of alkaline earth metal elements other than radium (Ra); B is one or more elements selected from a group consisting of elements of scandium (Sc), yttrium (Y) and lanthanoids; D is one or more elements selected from a group consisting of transition metal elements belonging to the fourth, fifth and sixth periods of the periodic table except platinum (Pt) and radioelements, and typical metal elements except 1A family elements, mercury (Hg), radium (Ra) and polonium (Po); and 0<x≦0.5, 0≦y≦0.5 and −0.05≦z≦0; and forming the interconnector film on the intermediate layer.
