PURPOSE: A separator for solid oxide fuel cell is provided to improve conductivity at high temperature, and chrome poisoning resistance, to be able to maximize cell performance of solid oxide fuel cell by preventing evaporation of chrome components in fuel cell. CONSTITUTION: A separator for solid oxide fuel cell comprises a metal substrate, a protective coating layer formed on the surface of the metal substrate. The protective coating layer comprises (Mn, Co)3O4 alloy phase, and one or more oxides of CoO, Co3O4,and NiCr2O4. A manufacturing method of the separator for a solid oxide fuel cell comprises: a step of spreading coating solution on a metal substrate, and drying the spread material; a step of reduction-heat-treatment the metal substrate; and a step of forming a protective coating layer by oxidation-heat-treatment the metal substrate in order to form the protective coating layer. |
