ABSTRACT:
A method for producing interconnectors for electrically connecting unit cells of a solid electrolyte type fuel cell. An interconnector material such as a perovskite complexed oxide is thermally sprayed onto the surface of an electrode of a solid electrolyte type fuel cell by plasma thermal spraying process at a temperature of not lower than 1,250.degree. C. to form an interconnector, and heat treated to diminish the cracks and defects resulting from the plasma thermal spraying process.
