Abstract: A composite coating layer for a solid oxide fuel cell member according to the present disclosure includes a nickel layer that coats at least a portion of the surface of the solid oxide fuel cell member, and a lanthanum oxide layer that coats at least a portion of the surface of the nickel layer, and thereby, has an effect of suppressing the volatilization of chromium from the solid oxide fuel cell member even under high temperature and long-term conditions.
