Abstract: A fuel cell includes a ceramic component and a sealing component. The sealing component includes a first glass-ceramic layer over the ceramic component and a second glass-ceramic layer over the first glass-ceramic layer, each of the first and the second glass-ceramic layers independently including between about 0.5% and about 50% glass phase content by volume. The first glass-ceramic layer includes a higher glass phase content than the second glass-ceramic layer, and between about 0.5% and about 10% glass stabilizer component by weight. In a method of sealing a ceramic component of a fuel cell, a first coat is applied over a first ceramic component of the fuel cell, the first coat including SiO2, and further including between about 0.5% and about 10% glass stabilizer component by weight. A second coat is applied over the first coat, the second coat including SiO2. The first and second coats are heated to form a sealing component, to thereby seal the ceramic component with the sealing component.
