Dense complex oxides films comprising conductive oxides and non-conductive oxides, method for preparing the same, and metallic interconnector using the same

摘要

The present invention relates to a thin film of a composite oxide having a dense structure including a conductive oxide and a non-conductive oxide, a method for manufacturing the same, and a metal connector using the same. According to the present invention, a conductive powder and a non-conductive powder having a dense structure formed by an aerosol deposition method are disclosed. The thin film of composite oxide not only reduces the price of raw powder compared to the conventional powder coating process, but also reduces the formation of metal oxide layer due to high temperature due to the small change of microstructure during long-term heat treatment, thereby reducing the area of high temperature and long heat treatment. It is possible to manufacture a conductive substrate having excellent stability by maintaining electrical conductivity having a specific resistance of 10 mΩ · cm 2 or less. Moreover, since it can be used for a long time at high temperature, it can be usefully used to improve long-term stability of the metal material connector of a low temperature solid oxide fuel cell (SoFC) used below 800 degreeC.;Aerosol deposition, composite powder, anti-oxidation, splicer, conductive oxide, metal substrate
