La0.6Sr0.4Co0.2Fe0.8O3 perovskite cathode for Intermediate Temperature Solid Oxide Fuel Cells: A comparative study
In this study the characteristics of two different kinds of La0.6Sr0.4Co0.2Fe0.8O3 (LSCF) powders, one in-house synthesized powder by a co-precipitation method and another one purchased from Fuel Cell Materials Co. (FCM Co., USA), were compared. The co-precipitated powder was prepared by using ammonium carbonate as precipitant with a NH4+/NO3- molar ratio of 2 and calcination at 1000C for 1 h....
متن کاملComposite Electrolytes and electrodes for Intermediate Temperature Hybrid Fuel Cells
Moving away from conventional solid oxide electrolytes, hybrid fuel cells based on composite electrolytes (a solid oxide electrolyte and a molten alkaline carbonate phase) exhibit promising performance due to the high electrolyte conductivity within the so-called intermediate temperature ranges (400-600 C). These electrolytes are a blend of those traditionally used in Solid Oxide and Molten Car...
متن کاملThermal expansion of doped lanthanum gallates
Thermal expansion of several compositions of Sr and Mg-doped LaGaO3 including an A-site deficient composition (La0⋅9Sr0⋅1)0⋅98(Ga0⋅8Mg0⋅2)O2⋅821 were measured in the temperature range from 298 to 1273 K. The effect of doping on thermal expansion was studied by varying the composition at one site of the perovskite structure (either A or B), while keeping the composition at the other site invaria...
