본 발명은 고체산화물 연료전지 금속분리판 표면에 스피넬 구조를 가지며 망간(Mn) 및 구리(Cu)를 함유하는 보호막을 코팅하여, 상기 금속분리판의 산화를 방지하여 계면 저항이 높아지는 것을 막을 수 있으며, 높은 전기전도도를 가짐으로써 고체산화물 연료전지의 효율을 증가시킬 수 있다.
The present invention relates to a ceramic powder for a protective film solid oxide fuel cell bipolar plate of metal, more specifically a first step of preparing a mixture by mixing with distilled water, the manganese compound and a copper compound; The mixture prepared in the first step is reacted with ethylene glycol and citric acid, a second step of preparing a sol (sol); A third step of forming a gel (gel) heating the sol prepared in the second step; A fourth step of heat-treating the gel (gel) formed in the third step of the primary; Comprises a ceramic powder production method for a solid oxide fuel cell bipolar plate protective film comprising a metal; and a gel (gel) to the second heat treatment to the ceramic a fifth step of fabricating a powder, the heat treatment in the fourth step.
The present invention can prevent the interface resistance increased by coating a protective film that has a spinel structure in the surface of the solid oxide fuel cell metal separator containing a manganese (Mn) and copper (Cu), preventing oxidation of the metallic bipolar plate , it is possible to increase the efficiency of the solid oxide fuel cell by having a high electrical conductivity.
