X-ray micro Laue diffraction tomography analysis of a solid oxide fuel cell1
The relevance of micro Laue diffraction tomography (µ-LT) to investigate heterogeneous polycrystalline materials has been studied. For this purpose, a multiphase solid oxide fuel cell (SOFC) electrode composite made of yttria-stabilized zirconia and nickel oxide phases, with grains of about a few micrometres in size, has been analyzed. In order to calibrate the Laue data and to test the techniq...
متن کاملA laboratory based system for laue micro x-ray diffraction.
A laboratory diffraction system capable of illuminating individual grains in a polycrystalline matrix is described. Using a microfocus x-ray source equipped with a tungsten anode and prefigured monocapillary optic, a micro-x-ray diffraction system with a 10 microm beam was developed. The beam profile generated by the ellipsoidal capillary was determined using the "knife edge" approach. Measurem...
متن کاملEnergy Price Analysis of a Biomass Gasification-Solid Oxide Fuel Cell-Gas Turbine Power Plant
In this study, effect of energy price on the development of a biomass gasification-solid oxide fuel cell-gas turbine hybrid power plant has been considered. Although, these hybrid systems have been studied based on sustainable approaches, economic aspects, specifically conventional energy prices, which are the principal bottleneck for the development of these new power generators, have attracte...
متن کاملSimulations of time-resolved x-ray diffraction in Laue geometry
A method for computer simulation of time-resolved x-ray diffraction (TRXD) in asymmetric Laue (transmission) geometry with an arbitrary propagating strain perpendicular to the crystal surface is presented. We present two case studies for possible strain generation by short-pulse laser irradiation: (i) a thermoelastic-like analytical model; (ii) a numerical model including the effects of electro...
متن کاملIn Situ X-ray and Electrochemical Studies of Solid Oxide Fuel Cell / Electrolyzer Oxygen Electrodes
The governing reaction mechanisms, and the electrode material compositions and structures, that controls the efficiency of the solid oxide fuel cells (SOFC) and solid oxide electrolysis cells (SOEC) need to be identified and well-understood for significant technological improvements. Our study on the oxygen electrodes focuses on specifically the effect of electrode crystal structure and morphol...
