Layered perovskite oxides have ordered A-cations localizing oxygen vacancies, and may potentially improve oxygen ion diffusivity and surface exchange coefficient. The A-site-ordered layered perovskite PrBa 0.5 Sr 0.5 Co 2 O 5+ı (PBSC) was evaluated as new cathode material for intermediate temperatur
