Effects of thermal aging on thermo-mechanical behavior of a glass sealant for solid oxide cell applications

An acoustic emission analysis of glass-ceramic sealants for solid oxide fuel and electrolysis cells exposed to torsional tests: Room and high-temperature experiments

“…These results, combined with mathematical computer models, provide a better comprehension of the stress distribution in the sealant and other components [5,32]. It has also been shown that thermal aging induced in a glass-ceramic material may cause a considerable increase in creep resistance but, in turn, a reduction in crack healing capacity [33]. The characterization of the chemical and mechanical behavior of the interface between the glass-ceramic sealant and metal interconnections should also be addressed, as the formation of coating layers, due to the interaction between them, can be detrimental to the system's integrity over time [34e36].…”
