Abstract
A solid oxide fuel cell electrolyte is fabricated by combining an yttria-stabilized zirconia powder with α-AlOhaving a dparticle size in a range of between about 10 nm and about 200 nm and MnOto form an electrolyte precursor composition, and then sintering the electrolyte precursor composition to thereby form the electrolyte. The α-AlOand MnOcan be present in the electrolyte precursor composition in an amount in a range of between about 0.25 mol % and about 5 mol %. The electrolyte can be a component of a solid oxide fuel cell of the invention.
