Oxide diffusion in innovative SOFC cathode materials.
Oxide diffusion was studied in two innovative SOFC cathode materials, Ba(2)Co(9)O(14) and Ca(3)Co(4)O(9)+δ derivatives. Although oxygen diffusion was confirmed in the promising material Ba(2)Co(9)O(14), it was not possible to derive accurate transport parameters because of an oxidation process at the sample surface which has still to be clarified. In contrast, oxygen diffusion in the well-known...
متن کاملSYNTHESIS AND CHARACTERIZATION HOLLOW SPHERICAL La0,7Sr0,2Ca0,1Co0,9Fe0,1O3–δ (LSCCT) FOR CATHODE OF SOLID OXIDE FUEL CELL (SOFC)
H. H. Yu, X. Li, Z. G. Yuan, School of Material Science and Engineering, Shenyang Ligong University, Shenyang, China Hollow spheres structures of La0,7Sr0,2Ca0,1Co0,9Fe0,1O3–δ (LSCCT) have been synthesized via hydrothermal method using carbon spheres as template. The structure and electrical conductivity of obtained samples are characterized by X-ray diffraction (XRD), scanning electron microsc...
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 ...
متن کاملBarium: An Efficient Cathode Layer for Bulk-heterojunction Solar Cells
We report Barium (Ba) cathode layer for bulk-heterojunction solar cells which enhanced the fill factor (FF) of p-DTS(FBTTh2)2/PC71BM BHJ solar cell up to 75.1%, one of the highest value reported for an organic solar cell. The external quantum efficiency exceeds 80%. Analysis of recombination mechanisms using the current-voltage (J-V) characteristics at various light intensities in the BHJ solar...
متن کاملSynthesis and characterization of novel Ge doped Sr1yCayFeO3 SOFC cathode materials
In this paper we report the successful incorporation of germanium into Sr1 yCayFeO3 d perovskite materials for potential applications as electrode materials for solid oxide fuel cells. It was observed that Ge doping leads to a change from a tetragonal cell (with partial ordering of oxygen vacancies) to a cubic one (with the oxygen vacancies disordered). Annealing experiments in 5%H2/95%N2 (up t...
