Nanocomposite nickel ceria cermet with low nickel content for anode-supported SOFCs

Abstract

Ni-ceria cermets with 7.5, 11, and 14 vol % of Ni manufactured by a novel method, called net-shape technology, are presented and evaluated. The method is a combination of conventional ceramic sintering and a polymer precursor impregnation technique. Ceria powder with a carbon pore former is sintered, constructing a rigid and stable oxide skeleton, which is next backfilled with Ni polymer precursor. The electrical conductivity of the cermets as a function of Ni content has been investigated. © 2005 The Electrochemical Society. All rights reserved.
