Abstract
A system consisting of a solid oxide electrolyte of the Ce0.9Gd0.1O2 − x (CGO) composition in contact with a two-layer cathode based on a nonstoichiometric composition (La0.8Sr0.2)0.95MnO3 ± δ (LSM1) and a stoichiometric perovskite La0.8Sr0.2MnO3 ± δ (LSM2) is prepared by the tape-casting process. It was shown that the best electrochemical characteristics are achieved for a three-layer system LSM2/{CGO-LSM1}/CGO sintered at 1410°C. The use of Ce-modified perovskites La0.8Sr0.2MnO3 ± δ and La0.6Sr0.6CoO3 ± δ as the collector layer of two-layer electrodes allows the electrochemical characteristics at moderately high temperatures (600–750°C) to be improved.
