Interconnect including lattice-type conductive core, oxidation-resistant insulating part, and oxidation-resistant conductive material layer for solid oxide fuel cell and method for manufacturing the same

A method for manufacturing an interconnect for a solid oxide fuel cell, the method comprising:

• forming a conductive core in a form of a lattice type plate having a plurality of hollow portions by sintering-molding a conductive powder having a melting point of 1000° C. or higher;
• molding an oxidation-resistant insulating part by wrapping the conductive core in an oxidation-resistant insulating ceramic powder to fill the hollow portions with the oxidation-resistant insulating ceramic powder, followed by sintering;
• exposing the conductive core to an external environment by mechanically processing a portion of the oxidation-resistant insulating part to expose a portion of the conductive core, which is to be connected with an electrode of the fuel cell;
• and
• coating an oxidation-resistant conductive material layer on an exposed portion of the conductive core by coating an oxidation-resistant conductive material on the exposed portion of the conductive core.
