Abstract:
1. A solid oxide fuel cell generator for electrochemically reacting a fuel gas with a flowing oxidant gas at an elevated temperature to produce power, said generator comprising a generator section receiving a fuel gas; a plurality of elongated fuel cells extending through said generator section and having opposing open fuel cell ends for directing an oxidant gas between opposing plena in said generator; a sealant defining a seal on said fuel cells adjacent at least one of said fuel cell ends, said sealant comprising a lanthanum borate aluminosilicate glass composition; wherein said fuel cells comprise a fuel electrode of nickel/yttria or scandia stabilized zirconia, an oxidant electrode of lanthanum manganite and an electrolyte of yttria or scandia stabilized zirconia, and said glass composition further comprises: La Al SrO present in an amount of between about 30 to about 40 mole %; ZrO at least one of YO MgO present in an amount of between about 10 to about 30 mole %; and wherein said glass composition includes B
