Recently, fuel cell has been studied from the viewpoint of environmental problems such as global warming and air pollution. Especially, the solid oxide fuel cell (SOFC) is promising, because it has the highest power generation efficiency among SOFC's. Zirconia-based ceramics have been often used as a SOFC electrolyte. Superplasticity has been found in many kinds of zirconia-based ceramics. To produce thin films or complex forms of the electrolyte by using superplastic phenomena is, therefore, very promising. A bonding of ceramics using superplastic ceramics as an interlayer has been reported such that the joint has a bonding strength almost equall to the strength of the ceramics itself. In this study, experiments to bond the electrolyte and electrodes using superplastic ceramics 5ScSZ powder as an interlayer was carried out.
