Sintering Behavior of Porous Nanostructured Sr-Doped Lanthanum Manganite as SOFC Cathode Material
The fuel cells are distinguished as generating of green allocable energy and are electrochemical devices of low environmental impact. Porous nanocrystalline strontium-doped lanthanum manganite La0.8Sr0.2MnO3 (LSM) cathode materials were prepared by mechanochemical route in various grinding times. Carbon black was employed to produce pores. The formation of LSM single phase was studied by X-ray ...
متن کاملMagnetic transitions and electrical transport in lanthanum strontium manganite: Effects of substitutions and high pressure
The observation of a substitution-induced ferromagnetic order ~Tc5200 K! is reported in antiferromagnetic La0.9Sr0.1MnO3 ~TN5130 K! when 0.05 of La is replaced by yttrium. Important results of ferromagnetic resonance ~FMR! and high-pressure transport studies are as follows. ~i! Data on FMR linewidth and resistivity provide evidence for the presence of microscopic magnetic inhomogeneities, possi...
متن کاملThermodynamic and kinetic assessments of strontium-doped lanthanum manganite perovskites for two-step thermochemical water splitting
Solar-driven thermochemical water splitting using non-stoichiometric oxides has emerged as an attractive technology for solar fuel production. The most widely considered oxide for this purpose is ceria, but the extreme temperatures required to achieve suitable levels of reduction introduce challenges in reactor design and operation, leading to efficiency penalties. Here, we provide a quantitati...
