Y and Zn co-doped Ba(Fe,Zr)O3−δ perovskite: A cobalt-free oxygen electrode material for the high-stable proton ceramic electrochemical cells

Developing active and durable oxygen electrodes for both oxygen reduction and oxygen evolution reactions at low temperatures remains a major challenge for proton ceramic electrochemical cells (PCECs). Herein, a cobalt-free Y and Zn co-doped Ba(Fe,Zr)O 3−δ perovskite (BFZYZ) is de...
