Abstract: 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.

Abstract: A method for coating a metallic connector for solid oxide fuel cell is provided to improve electric conductance in the high temperature oxidizing atmosphere by coating cobalt forming a spinel layer through pulse plating on the surface of the metallic connector and to improve output performance and endurance of a solid oxide fuel cell by preventing the contamination of air pores. A method for coating a metallic connector for solid oxide fuel cell includes the steps of removing impurity adhered to the surface of a metallic connector by placing cobalt as an anode(2) and the metallic connector as a cathode(3), setting up an average current density in a cobalt plating solution of the room temperature, regulating peak current density, current application time and current interception time, and performing pulse plating. The peak current density is 100~250mA/cm^2, current application time is 0.002~0.005 seconds, and current interception time is 0.005~0.008 seconds.
