A Durable and Highly Active Oxygen Electrode for Solid Oxide Cells: New Insight into Segregation Suppression of Layered Perovskite

at 650 °C in the single cells of oxygen ion and proton type, respectively. This paper provides new insights into segregation suppression in layered perovskite and offers theoretical guidance for the rational design of oxygen electrodes to achieve high Cr-tolerance and catalytic activity.
