Zusammenfassung:	A solid oxide fuel cell stack having a plurality of cassettes and a compliant glass seal disposed between the sealing surfaces of adjacent cassettes, thereby joining the cassettes and providing a hermetic seal therebetween. The compliant glass seal may include a glass, at least one metal selected from Groups 9, 10, and 11 of the periodic table, and fibers of yttria-stabilized zirconia (YSZ) to enhance the desirable properties of the compliant glass seal. The combined weight percentage of the at least one metal and YSZ in the compliant glass seal is 30 to 42.5 weight percent, preferably 37.5 percent.
