A novel layered perovskite oxide PrBaCuCoO 5+ı (PBCCO) is employed as a potential cathode for intermediate-temperature solid oxide fuel cells (IT-SOFCs). Thermal expansion and electrochemical performance on samarium-doped ceria (SDC) electrolyte are evaluated. The thermal expansion coefficient (TEC)
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
