“…The state of art lanthanum strontium manganite (LSM) has been considered as the mixed conducting electrode in yttria-stabilized zirconia (YSZ) based SOFCs, but its electrocatalytic activity decreases significantly owing to sluggish oxygen reduction reaction kinetics [5]. Hence, considerable efforts are being made to develop a new class of perovskite based materials such as iron and cobalt containing La 1À x Sr x Co 1À y Fe y O 3À δ .…”

“…The La 0.8 Sr 0.2 Mn0 3 gives a good combination of electronic conductivity and expansion coefficient matching, and is now available commercially for SOFC applications. Higher conductivity can be obtained at higher dopant levels, but the expansion coefficient then becomes too high [12][13][14][15][16][17][18][19][20] . There are several routes to synthesize perovskite structured materials.…”

Polycrystalline strontium-doped lanthanum manganite (LSM) powders with 0.15, 0.22, and 0.30 mol % Sr were synthesized by the polymeric precursor route using a molar ratio of 3:1 citric acid and metal cations. The powders were characterized by Fourier transform infrared spectroscopy, thermal analysis, high-temperature X-ray diffraction to determine the crystalline perovskite phase and crystallite sizes, scanning electron microscopy for the morphological analysis, nitrogen adsorption to determine the specific surface area, and laser scattering to evaluate the particle size distribution. The LSM perovskite-type oxides containing intermediate 0.22 mol % Sr were found to exhibit a tendency to decrease in crystallite size and increase in specific surface area and, when calcined at 700-900 °C exhibited a pure phase of perovskite, had a crystallite size of about 17-20 nm and a specific surface area for 900 °C of 34.3 m 2 .g -1.
