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 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...
متن کاملConductivity and switching phenomena in Mn-doped perovskite single crystals and manganite thin films
For better understanding of the charge-transport mechanisms in perovskite manganites, along with colossal magnetoresistance ~CMR! materials, such as La12xSrxMnO3, we study systems with decreased content of Mn ions, such as single crystals of LaGa12xMnxO3 (0,x,0.5). The conductivity of all the systems in study can be described adequately with a nonadiabatic approximation of the hopping model wit...
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 ...
