49th International Conference on Environmental Systems


Glass-based sealing materials are preferred for hermetic sealing of high temperature electrochemical devices due to flexibility in tuning the thermophysical properties by formulation chemistry. Ease of manufacturing and application are the other major advantages of glass seals and a number of glass systems have been reported as sealants for solid oxide electrochemical systems. Recent developments in sealing materials for oxygen separation and compression will be presented with focus on chemical and structural stability of electrode–seal and electrolyte–seal interfaces. The similarities and contrasts between the sealing materials for oxygen compressors and fuel/electrolysis cell systems will be discussed. Seal properties will be discussed with regards to constituent materials such as glass network formers, modifiers, additives, and intermediate oxides.
