SEPARATOR FOR SOLID OXIDE FUEL CELL COMPRISING NANO-SIZED OXIDE DISPERSION FERRITIC STEELS AND MANUFACTURING METHOD THEREOF

摘要

The present invention relates to a separation plate for a solid oxide fuel cell including ferrite steel in which nano-oxides are dispersed, and a method for manufacturing the same. More particularly, an alloy sintered body obtained by compressing and sintering nano-CeO_2 or LaCrO_3 in a form of pellets after dispersing nano-CeO_2 or LaCrO_3 in SUS430 power is very stable and does not react with the base steel, and is compatible with other SOFC components regarding thermal expansion coefficient. By greatly enhancing the performance of SUS430 over long-term area resistivity values, and having excellent chemical and thermal compatibility and better oxidation characteristics, alloys with nano-CeO_2 and LaCrO_3 dispersions can be usefully used as SOFC coupling materials.
