The objective of this work is to complete the development of soft glass-ceramic sealants for the solid oxide fuel cell (SOFC). Among other requirements, the materials must soften at the operation temperature of the fuel cell (600--1,000 C) to relieve stresses between stack components, and their thermal expansions must be tailored to match those of the stack materials. Specific objectives included addressing the needs of industrial fuel cell developers, based on their evaluation of samples the authors supply, as well as working with commercial glass producers to achieve scaled-up production of the materials without changing their properties. Results from long-term stability testing, stability in voltage gradients, thermal expansion and softening, and scaled-up production methods are presented.
