Abstract
Glass-ceramic sealant is disclosed for planar solid oxide fuel cells. The glass-ceramic sealant includes 0 to 40 mol % of silicon oxide, 0 to 15 mol % boron oxide, 0 to 10 mol % of aluminum oxide, 0 to 40 mol % of barium oxide, 0 to 15 mol % of calcium oxide, 0 to 15 mol % of lanthanum oxide and 0 to 5 mol % of zirconium dioxide. At 0° C. to 600° C., the thermal expansion coefficient of the sealant is 8 to 10 ppm/° C.
