SEGMENTED-IN-SERIES SOLID OXIDE FUEL CELL CERAMIC INTERCONNECTS AND FABRICATION METHOD OF CERAMIC INTERCONNECTS DECALCOMANIA PAPER

摘要

The present invention relates to a ceramic connection material for a segmented-in-series solid oxide fuel cell (SIS-SOFC) and to a manufacturing method of ceramic connection material decalcomania paper. In the manufacturing method of ceramic connection material decalcomania paper, a ceramic composition has a perovskite structure for the ceramic connection material of the SIS-SOFC to which CaF_2 and MgF_2 are added as a sintering aid, containing a small amount of fluoride, or an element with strong reduction is located in the same valence, improving a high conductivity between 750 and 850 degrees Celsius in oxidation and reduction atmosphere while manufacturing connection material powders to be sintered at low temperatures, thereby enabling the connection material powders to be manufactured as a decalcomania paper and being stacked in a certain thickness.
