THE MANUFACTURING METHOD OF FLAT TUBULAR SUPPORT FOR SEGMENT-IN-SERIES TYPE SOFC AND THE FLAT TUBULAR SUPPORT MADE BY THE SAME

摘要

The present invention relates to a flat tubular support for segment type solid oxide fuel cells, and a support manufactured thereby. The method comprises the steps of: mixing activated charcoal powder to 100 wt% of YSZ; equalizing the mixture in sludge state by ball milling; pulverizing the mixture after drying; making paste by mixing the powdered mixture with a binder, a plasticizer, a lubricant, and a solvent; extruding the paste in a flat tubular support; drying the extruded flat tubular support by using a thermo-hygrostat; pre-plasticizing the dried flat tubular support by a thermal treatment; and plasticizing the pre-plasticized flat tubular support.
