Composites for thermal expansion matched oxygen electrodes (2019-2023)

This project aims to develop high performance composite oxygen electrodes by using both negative thermal expansion materials and electrolyte materials to tailor the thermal expansivities and activities of the perovskite-based electrodes for reduced temperature solid oxide cells . Such composite electrodes will show highly matched thermal expansion with electrolyte without sacrificing the high activity at reduced temperatures. This project thus addresses an important practical issue - thermal expansion compatibility, and is of great significance to the solid oxide cells industries.
