Synthesis and electrochemical characterization of La0.75Sr0.25Mn0.5Cr0.5‐xAlxO3, for IT- and HT- SOFCs
MetadataShow full item record
The main emphasis of this work is to create a new perovskite material with three different compositions (La0.75Sr0.25Mn0.5Cr0.5‐xAlxO3, x = 0.1, 0.2, 0.3) applied in both Intermediate and high Temperature ‐ Solid Oxide Fuel Cells (IT & HT‐SOFCs). Perovskite‐type polycrystalline La0.75Sr0.25Mn0.5Cr0.5‐xAlxO3‐δ (x = 0.1, 0.2, 0.3) powders were synthesized and formed in a single phase structure by a dry chemistry route (standard solid‐state reaction method). The effect of Al‐doping on physicochemical and surface properties has been discovered. The compounds were crystallized in single phase rhombohedral symmetry (R‐3C Space. Group). Total conductivity of Al‐doping in wet 5% H2 was higher than both dry 5% H2 and air. The obtained results enhance the electro‐catalytic performance and the material conductivity as well, which will be good for anode materials in IT‐ HT‐SOFCs and the optimum doping is 10%.
