摘要：
A solid oxide fuel cell electrolyte is fabricated by combining an yttria- stabilized zirconia powder with α- Al
2 O
3 having a d
5o particle size in a range of between about 10 nm and about 200 nm and Mn
2 O
3 to form an electrolyte precursor composition, and then sintering the electrolyte precursor composition to thereby form the electrolyte. The α- Al
2 O
3 and Mn
2 O
3 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.
