Abstract
⺠A-site non-stoichiometric solid solutions, Sr1.5LaxMnO4(x = 0.35, 0.40, 0.45) were prepared and employed as IT-SOFC cathode material. ⺠Sr1.5La0.35MnO4 cathode gave the lowest polarization resistance value of 0.25 Ω cm2 at 750 °C. ⺠The charge transfer process is the reaction rate limiting step for Sr1.5La0.35MnO4 cathode. ⺠The oxygen vacancies generated by the A-site La cation deficiencies promoted the oxygen reduction reaction on Sr1.5La0.35MnO4 cathode.
