PURPOSE: Interconnector surface treatment of solid oxide fuel cell is provided to reduce the contact resistance between interconnector and fuel cell and to improve output performance when the solid oxide fuel cells are laminated. CONSTITUTION: A method for treating interconnector surface comprises the following steps of: sand-blasting a base material of Crofer 22 APU as the interconnector of solid oxide fuel cell; spraying a coating slurry comprising (La0.85Sr0.15)0.9MnO3 or La0.8Sr0.2CoO3; and heat-treating the formed ceramic coating layer under inert gas atmosphere, or reduction atmosphere of nitrogen and hydrogen. In the sand-blasting step, the sand with 80-120mesh is used. |
