摘要
Provided are a metallic connecting material for a solid oxide fuel cell which is excellent in oxidation resistance and high temperature conductivity, and a method for coating the metallic connecting material. The metallic connecting material is a ferrite-based stainless steel sheet whose surface is coated on a cobalt coating layer having a thickness of 1-10 micrometers and a lanthanum coating layer having a thickness of 50-1,000 Angstrom. The method comprises the steps of forming a cobalt coating layer on the surface of a ferrite-based stainless steel sheet by an electron beam vapor deposition; and forming a lanthanum coating layer on the cobalt coating layer by an electron beam vapor deposition.
