Heating device of metallic interconnect for solid oxide fuel cell and coating method of the interconnect using the same

摘要

A heating device of metallic interconnect is provided to form a dense coating layer minimizing micropore or microcrack on the metallic interconnect, to reduce the loss of output in operation of a solid oxide fuel cell, and to maintain long term endurance and performance of the metallic interconnect. A heating device of metallic interconnect(1) for a solid oxide fuel cell comprises a flat heating plate(11) which is mounted with the metallic interconnect and heats the metallic interconnect to 150~300 °C; a heating unit(12) which includes a heater(12a) providing the to the heating plate and a control part(12b) controlling a heating temperature; an insulating member(13) insulating a part which does not contact with the heating plate of the heater on the bottom surface of the heater; a case(14) accommodating the heating plate, heater and insulating unit; and a clamp(15) fixing the metallic interconnect on the heating plate.
