Probing the Mechanisms and Control of Catalytic Activity of Perovskite SOFC Anode Materials through In-Situ Dissolution-Exsolution Studies

Professor John Irvine, Dr Ivan Da Silva Gonzalez, Mr Robert Price, Dr Julia Payne & Mr Stewart Dickson
Electrode materials for devices such as solid oxide fuel cells must be catalytically active and good ionic and electronic conductors. In particular, recent work in our laboratories has shown that A-site deficient perovskite oxides exhibit excellent performance when used in devices such as solid oxide fuel cells. Two contrasting methods for the synthesis of such perovskites are a conventional ¿exsolution¿ method, or a ¿dissolution-exsolution' method. The aim of this experiment is to probe the mechanism...
