The Hebb–Wagne rpolarization method with the electron blocking electrode has been discussed in this paper in aim to determine a partial ionic conductivity of Sr-doped lanthanum manganite.The “limiting current” in the proposed system was measured using the two-point DC technique with additional Pt electrode between LSM and blocking electrode.The electrochemical model based on bulk diffusion processes and Boltzmann statistics has been also described. The ionic conductivity calculated with the use of proposed model for La0.7Sr0.3MnO3þδ was5.3104 S cm1 at 800 °C and the activation energy of ionic conductivity was found to be (0.6070.02) eV.This result is in agreement with previous literature reports and indicates the workability of the modified Hebb–Wagner system.
