This project aims to develop high performance composite oxygen electrodes by using both negative thermal expansion materials and electrolyte materials to tailor the thermal expansion and activities of the perovskite-based electrodes for use in reduced temperature solid oxide cells. Such composite electrodes will show highly matched thermal expansion with electrolyte without sacrificing high activity at reduced temperatures. This project seeks to address an important practical issue in the operation of solid oxide power cells - thermal expansion compatibility, which causes poor efficiency outside a narrow temperature band.

该项目旨在通过使用负热膨胀材料和电解质材料来开发高性能复合氧电极，以定制用于低温固体氧化物电池的钙钛矿基电极的热膨胀和活性。这种复合电极将显示出与电解质高度匹配的热膨胀，而不会牺牲在降低的温度下的高活性。该项目旨在解决固体氧化物动力电池运行中的一个重要实际问题-热膨胀兼容性，这会导致在狭窄的温度带之外效率低下。
