High-entropy engineering tuning electrochemical activity and stability of a layered double perovskite oxygen electrode for high-performance protonic ceramic cells
A high-entropy perovskite Pr 0.2 La 0.2 Sm 0.2 Nd 0.2 Gd 0.2 BaCo 2 O 5+ δ is developed as a high-performance oxygen electrode material for PCCs with enhanced proton uptake capacity, higher concentration of oxygen vacancies, and improved thermal stability.
