Effective enhancement of electrochemical properties of LSM oxygen electrode in SOCs by LNO nano-catalyst infiltration
In this paper, the effects of infiltration of La2NiO4 (LNO) as a mixed ionic and electronic conductor (MIEC) on the electrochemical performance of porous strontium doped lanthanum manganite (LSM) oxygen electrode of solid oxide cells, in the temperature ranges of 650-850 °C, is reported. XRD and FE-SEM results of the LNO sample calcined at 900 °C confirmed the formation of single phase LNO nano...
متن کاملسنتز نانو بلورکهای lsm (lanthanum strontium manganite) به منظور استفاده درکاتدپیل سوختی اکسید جامد
در این پژوهش سنتز نانو بلورک های lsm (lanthanum strontium manganite) به منظور استفاده درکاتد پیل سوختی اکسید جامد به روش هم رسوبی مورد بررسی قرار گرفته است. اکسید لانتانیوم (la2o3)، کربنات استرانسیوم (srco3) و کربنات منگنز آبدار (mnco3.xh2o) به عنوان ماده اولیه انتخاب گردیده است. برای ایجاد محلول های نیترات لانتانیوم، نیترات استرانسیوم و نیترات منگنز، مقادیر توزین شده اولیه در اسید نیتریک غلیظ ...
15 صفحه اولnbiased characterization of three-phase microstructure of porous lanthanum oped strontium manganite/yttria-stabilized zirconia composite cathodes for olid oxide fuel cells using atomic force microscopy and stereology
Microstructural characteristics of porous LSM/YSZ composite cathodes greatly influence the performance of solid oxide fuel cells. The triple phase boundaries, for example, account for a significant portion of the electrochemically active sites in these porous composite cathodes. Nonetheless, experimental characterization of the relevantmicrostructural attributes has been problematic due to lack...
متن کاملCorrelating surface cation composition and thin film microstructure with the electrochemical performance of lanthanum strontium cobaltite (LSC) electrodes
La0.6Sr0.4CoO3 d thin films of varying thicknesses (20–170 nm) were prepared by pulsed laser deposition on yttria-stabilized zirconia (100) substrates, and their electrochemical electrode performance was correlated with the chemical surface composition and microstructure (e.g. porosity, surface area). The surface cation composition was analyzed by an atomic etching procedure with on-line induct...
متن کاملSintering 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 ...
