固体氧化物燃料电池中的陶瓷材料
Ceramic Materials for Solid Oxide Fuel Cell
摘要
Abstract
Solid oxide fuel cell (SOFC) is known as a ceramic fuel cell. The key components including electrolyte, cathode and anode are ceramic materials. The dense electrolyte film requires a pure oxygen ion conductivity. In general, the oxygen ion conductivity is mainly derived from the oxygen vacancy in oxide materials by doping lower valence metallic ions. Fluorite structured Y2O3 stabilized ZrO2 (YSZ) and Sc2O3 stabilized ZrO2 (ScSZ) are the main electrolyte materials for industrial application. The doped CeO2,δ-Bi2O3 and doped LaGaO3 perovskite, with a higher oxygen ion conductivity, have a potential application for SOFC at a lower temperature. The electrodes are porous ceramic materials with oxygen ion and electron conductivity. Ni-YSZ cermet has been used in industries due to its high electrochemical performance. The perovskite materials with a mixed ionic and electronic conductivity (MIEC) have attracted considerable attention because of their potential applications in SOFC under hydrocarbon fuels. Doped LaMnO3-YSZ composite ceramic is a widely used cathode material for high-temperature SOFC, having a high electrochemical performance and a good stability in long-term operation. While the doped LaFeO3, especially La0.6Sr0.4Co0.2Fe0.8O3, is used in intermediate-temperature SOFC, also showing good electrochemical activity and stability. Moreover, optimizing the composition and structure of cathode material remains a research focus for the development of SOFC.关键词
