Development of new functional materials with improved characteristics for solid oxide fuel cells (SOFCs) and solid oxide electrolysis cells (SOECs) is one of the most important tasks of modern materials science. High electrocatalytic activity in oxygen reduction reactions (ORR), chemical and thermomechanical compatibility with solid electrolytes, as well as stability at elevated temperatures are the most important requirements for cathode materials utilized in SOFCs. Layered oxygen-deficient double perovskites possess the complex of the above-mentioned properties, being one of the most promising cathode materials operating at intermediate temperatures. The present review summarizes the data available in the literature concerning crystal structure, thermal, electrotransport-related, and other functional properties (including electrochemical performance in ORR) of these materials. The main emphasis is placed on the state-of-art approaches to improving the functional characteristics of these complex oxides.
开发具有改进特性的新型功能材料用于固体氧化物燃料电池（SOFC）和固体氧化物电解池（SOEC）是现代材料科学最重要的任务之一。在氧还原反应（ORR）中具有高电催化活性、与固体电解质的化学和热机械兼容性以及在高温下的稳定性是SOFC中使用的阴极材料的最重要要求。层状缺氧双钙钛矿具有上述性能的综合，是在中温下运行的最有前途的阴极材料之一。本综述总结了文献中有关这些材料的晶体结构、热、电输运相关及其他功能特性（包括ORR中的电化学性能）的可用数据。主要重点放在改善这些复合氧化物功能特性的最新方法上。
