The Conductivity of Co-dopant Ceria Electrolyte

摘要

A kind of novel ceria electrolyte was examined. Various trivatent oxides were added as co-dopants to Ce_(0.8) Gd_(0.2) O_(1.9) and their effects on the conductivity of ceria electrolyte mere discussed. It has been found that the co-dopant of trivalent oxides of Sm, Nd, La and Y improves the ionic conductivity notably. Furthermore, the fine original powders , co-dopant and higher sintering temperature may hasten the sintering.
