Title of Invention	CO-DOPED YSZ ELECTROLYTES FOR SOLID OXIDE FUEL CELL STACKS
Abstract	A solid oxide fuel cell electrolyte is fabricated by combining an yttria- stabilized zirconia powder with α- Al2O3 having a d5o particle size in a range of between about 10 nm and about 200 nm and Mn2O3 to form an electrolyte precursor composition, and then sintering the electrolyte precursor composition to thereby form the electrolyte. The α- Al2O3 and Mn2O3 can 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.
