Electrical and thermal properties of Sr-doped lanthanum manganites

Characterization of mechano-thermally synthesized Curie temperature-adjusted La0.8Sr0.2MnO3 nanoparticles coated with (3-aminopropyl) triethoxysilane

“…Using a linear extrapolation to this plot, the slope gives a quantity proportional to the reciprocal of the crystallite size Kλ L À Á [20,21]. Since the heat-treated samples were relieved from residual stored strain, in order to estimate their mean crystallite sizes, the following method which does not take into account the strain broadening due to strain, was utilized.…”

“…It is now considered to be a very promising cathode in solid oxide fuel cells (SOFCs) due to its high electrical conductivity and good chemical and thermal compatibilities with zirconia electrolytes [20,21]. SOFCs are environmentally-friendly energy conversion devices with high efficiency and long stability as well as capability to be used in Materials Characterization 106 (2015) 78-85 high temperatures.…”

Sr2Fe1.5Mo0.5O6 as Cathodes for Intermediate-Temperature Solid Oxide Fuel Cells with La0.8Sr0.2Ga0.87Mg0.13O3 Electrolyte

“…10 The conventional cathode material La 1-x Sr x MnO 3 (LSM) is a poor ionic conductor. 11 The active reaction site of oxygen reduction is restricted to the triple phase boundaries (TPBs) at the cathode-electrolyte physical interface. The activation polarization loss of LSM cathode is significant when the cell operating temperature is reduced, making it not suitable as cathode material for IT-SOFCs.…”

Effect of preparative methods on electrical and electrochemical performance of lanthanum strontium manganite

“…The LaMnO 3 , LM, with perovskite structure can tolerate a considerable portion of vacancies at the La 3+ site giving rise to compositions of La (1−δ) MnO 3 type with the charge compensated by the conversion of Mn 3+ to Mn 4+ [1]. Lanthanum strontium manganite, LSM, has been considered as one of the most promising cathode materials for solid oxide fuel cell (SOFC) applications due to its high electrode activity for the oxygen reduction reaction, high electronic conductivity, and chemical as well as mechanical compatibility with the established solid electrolytes [2].…”
