✦ Synopsis

A-site non-stoichiometric materials Sr 1.5 La x MnO 4 (x = 0.35, 0.40, 0.45) are prepared via solid state reaction. The structure of these materials is determined to be tetragonal. Both the lattice volume and the thermal expansion coefficient reduce with the decrease of lanthanum content. On the contrary, the conductivity increases and the maximum value of 13.9 S cm -1 is found for Sr 1.5 La 0.35 MnO 4 at 750 β€’ C in air. AC impedance spectroscopy and DC polarization measurements are used to study the electrode performance. The optimum composition of Sr 1.5 La 0.35 MnO 4 results in 0.25 cm 2 area specific resistance (ASR) at 750 β€’ C in air. The oxygen partial pressure measurement indicates that the charge transfer process is the rate-limiting step of the electrode reactions.
