Evaluation of A-site Ba-deficient PrBa0.5-xSr0.5Co2O5+δ (x = 0, 0.04 and 0.08) as cathode materials for solid oxide fuel cells

•Ba-deficient PrBa0.5-xSr0.5Co2O5+δ perovskites were studied as IT-SOFC cathode.•Introduction of Ba deficiency promotes the formation of oxygen vacancies.•PB0.5-xSCO oxides have good chemical compatibility with LSGM electrolyte.•Ba deficiency is beneficial to the electrochemical performance of PB0.5...
