The feasibility and opportunity of nanostructured defect-engineered electrodes for exceptional performance stability solid oxide fuel cells operating at intermediate temperatures (500–700°C) are reported in this study. electrode is designed with infiltrated La0.4Sr0.6MnO3-δ (LSM) nanoparticles as oxygen reduction reaction catalysts on an yttria-stabilized zirconia (YSZ) nanofiber scaffold a con...

Nanocomposite electrodes of (Sr0.7Pr0.3)0.95TiO3±δ−Ce0.9Gd0.1O1.95 are directly prepared by spray-pyrolysis deposition on Zr0.82Y0.16O1.92 electrolytes and their properties compared with those obtained the traditional screen-printing powder method. The structural, microstructural electrical characteristics investigated for potential use as both cathode anode in Solid Oxide Fuel Cells. nanocompo...

In this article we review work on oxyanion (carbonate, borate, nitrate, phosphate, sulphate, silicate) doping in perovskite materials beginning with early work on doping studies in superconducting cuprates, and extending to more recent work on doping into perovskite-type solid oxide fuel cell materials. In this doping strategy, the central atom of the oxyanion group occupies the perovskite B ca...

in this work, the strontium-doped lanthanum manganite- a ceramic material- used as cathode in solid oxide fuel cells. an impression of grinding time on the structural and thermal properties of sr-doped lamno3 system with la1-xsrxmno3 (x=0.2) stoichiometric ratio was investigated. the nano crystallite lsm powder with cubic structure was prepared by varying the milling time of planetary monomill ...

an efficient procedure is presented for the evaluation of solid oxide fuel cell (sofc) anode microstructure triple phase boundary length (tpbl). triple phase boundary- the one that is common between three phases of the microstructure- has a great influence on the overall efficiency of sofc because all electrochemical reactions of anode take place in its vicinity. therefore, evaluation of tpbl f...
