The transport parameters of La Sr Co Fe O were determined by electrical conductivity relaxation and high 0.6 0.4 0.6 0.4 32d temperature coulometric titration experiments. The experimental response curves were analyzed in the frequency domain. The results obtained by both methods were in good agreem
Oxygen permeation measurements were made on dense discs of SrCo,,,Fe,,,O,\_, as a function of pressure gradient, 0.01 to 1 atm, temperature, 775 to 870°C and disc thickness, 1 to 2.6 mm. Two different measuring configurations were used: with the pressure gradient applied parallel to the disc axis an
