Title:

MANUFACTURE OF INTERCONNECTOR FOR SOLID ELECTROLYTE TYPE FUEL CELL

Document Type and Number:

Japanese Patent JPH0644991

Kind Code:

A

Abstract:

PURPOSE: To attain mass production of a large area interconnector with air- tightness, no generation of fuel leakage, and that can be made into a thin film in the manufacture of interconnector for a solid electrolyte type fuel cell.

CONSTITUTION: A material for an interconnector is thermally sprayed on the surface of electrode for a solid electrolyte type fuel cell so as to form a spray deposit for being subjected to heat treatment in order to form the interconnector. This heat treatment is desirably performed at a temperature of 1250°C or more. A perovskite complex oxide expressed in the form of ABO3 is desirable as the material of interconnector.
