Summary

A self healing glass-sealing concept is developed and used for making metal-glass-ceramic seals for potential application in solid oxide fuel cells (SOFC) in order to enhance reliability and life of cell. In this study, a glass displaying self-healing behavior is used to fabricate seals and performance of these seals under long-term exposure at higher temperatures coupled with thermal cycling are characterized by leak tests. Self healing ability of these glass seals is also demonstrated by leak rate measurements. These results demonstrated excellent performance and self-healing ability of the seals for times exceeding 2500 hours and 275 thermal cycles between 25°C and 800°C.
