Abstract:
A glass-ceramic seal for ionic transport devices such as solid oxide fuel cell stacks or oxygen transport membrane applications. Preferred embodiments of the present invention comprise glass-ceramic sealant material based on a Barium-Aluminum-Silica system, which exhibits a high enough coefficient of thermal expansion to closely match the overall CTE of a SOFC cell/stack (preferably from about 11 to 12.8 ppm/° C.), good sintering behavior, and a very low residual glass phase (which contributes to the stability of the seal).
