【 摘 要 】

tsSynthesis of high-entropy perovskite oxide for air electrode in reversible proton ceramic electrochemical cells.Triple-conducting high-entropy air electrodes exhibit excellent structural stability and oxygen catalytic activity.The peak power density and current density of the cell with high-entropy air electrode in the fuel cell and electrolysis modes are 1.21 W cm−2 and − 1.95 A cm−2 at 600 °C, respectively.
