Summary

To achieve the high power densities in planar solid oxide fuel cell (SOFC) stacks, reliable seal technology is required. Current seal technology has been successful in laboratory stack testing, but in practice is hampered by reliability and lifetime issues, particularly with respect to thermal cycling. A composite approach, in which a crystalline ceramic phase is dispersed in a compliant viscous matrix, can potentially achieve good thermal, mechanical, and chemical stability through the stress relief and self-healing character of the viscous seal material and the interlocking nature of the crystalline phase. In this program, NexTech Materials has developed and tested a range of seal materials for application in SOFC stacks. This presentation will highlight our seal development effort to date.
