    摘要： The invention is directed to highly crystalline, frit-sintered glass-ceramic materials and seals made using them that are suitable for solid oxide fuel cell applications. The seals have a coefficient of thermal expansion in the range of 70-130×10−7° C., preferably 85-115×10−7° C. The glass-ceramic materials have a crystalline component and a glass component, the crystalline component being >50% of the glass-ceramic and the glass component being 75%. Regarding the crystalline component only, >50% of the crystals in the crystalline component of the glass-ceramic has a structure selected from the structural groups represented by walstromite, cyclowollastonite, μ-(Ca,Sr)SiO3, kalsilite, kaliophilite and wollastonite (the primary crystalline phase) and the remaining

    摘要： Disclosed are seals and seal structures for use in electrochemical devices such as solid oxide fuel cell devices. Exemplary seal structures are configured such that at least a portion of the interface between the seal and electrolyte sheet deviates from planarity by extending either (i) upwardly and inwardly (ii) or downwardly and inwardly, toward the active portion of the electrolyte sheet surface where one or more device electrodes are deposited. By angling the seal portion of the electrolyte sheet, the sharpness of any resulting bends or deformations that may occur during use can be reduced, thus reducing the likelihood of any cracks forming in the typically high stress regions of the electrolyte sheet. Further, preferably at least a portion of the electrolyte sheet contacting the seal composition, the seal-electrolyte interface may deviate from planarity by at least 0.1 mm from the seal-electrolyte interface, where the deviation from planarity extends normal to the seal or inwardly toward the active surface region of the electrolyte sheet. Also disclosed are methods for manufacturing the inventive seal structures and electrochemical device assemblies comprising same.
