Beschreibung
Zusammenfassung:	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.
