Abstract
The sintering characteristics of Ce0.9Gd0.1O1.95 (CGO) with various specific surface areas and Zr0.89Sc0.1Ce0.01O1.95 (ScSZ) content have been measured. Cobalt-doped CGO can be used as a buffer layer on a ScSZ electrolyte for anode-supported solid oxide fuel cells with intermediate-temperature operation. By addition of ScSZ, the densifications of all CGO samples were markedly lowered. The Co-doping of CGO enhanced its densification and improved the increase of densification with increasing specific surface area.
