8. Interaction of Glass Seals/Electrodes and Electrolytes

SOFC contains solid electrolyte, which reduces any material corrosion problems along with the increased portable applications. A good/ideal SOFC electrolyte has high ionic conduction, no electronic conduction, good mechanical properties, and stability in reducing as well as oxidising atmospheres. The compatibility electrolytes with the adjoining components of SOFC play a key role in determining the cell efficiency. Hence, research is being pursued for fabricating the electrolytes which can be used for low temperature–intermediate temperature applications. High temperature SOFC enhances the fuel flexibility, whereas low temperature SOFC relaxes stringent material requirements. This chapter focuses around the compatibility of different electrolytes with the sealants glasses and electrolytes.
