ABSTRACT:
A method for producing an airtight and thin lanthanum chromite film having a splendid electrical conductivity including providing an air electrode film on a porous ceramic substrate, thermally spraying a raw material for thermally spraying lanthanum chromite on a surface of the air electrode film to form a thermally sprayed film, and heat treating the thermally sprayed film to form an interconnector. The raw material for thermally spraying lanthanum chromite may contain a doping metal or metals, such as, copper, and zinc, etc. The heat treating is effected preferably at a temperature of at least 1,250.degree. C.
