N2 - Electroconductivity of SrTi1-x Fe x O 3-δ(x = 0-0.5) specimens was studied by four-probe method. An opportunity was studied to produce hydrogen by high-temperature electrochemical conversion using SrTi0.5Fe0.5O3-δ as the membrane material of the best conductivity. The effective ambipolar conductivity values calculated for SrTi0.5Fe0.5O3-δ from the leakage experiment were found different from the ambipolar conductivity values calculated by the four-probe data processing because ambipolar conductivity corresponds to bulk transfer of complex oxide particles, taking no surface phenomena into account.
