Defect Chemistry of P-Type Perovskite Conductor Used in Solid Oxide Fuel Cells

Abstract

A strict materials section is of great importance for the electrode of solid oxide fuel cells (SOFC) operated over the intermediate temperature region (500° to 700°C), which seems mandatory for SOFC commercialization. Therefore, it is necessary to study the electrode materials by understanding the mechanisms for the conductive and catalytic behavior and developing the reliable and stable experimental methods to measure defect density and catalytic ability. the global solutions to defect chemistry models, was discussed, with an emphasis on the p-type perovskite conductors, which are considered as the electrodes of SOFC. the global defect chemistry models allow better understanding and prediction of the electrochemical properties of p-type conductors. Experiments were performed to further understand the models and to search for the new generation of the electrode materials. This is an abstract of a paper presented at the 228th ACS National Meeting (Philadelphia, PA, 8/22-26/2004).
