چکیده
Solid oxide cells are an exciting technology for energy conversion. Fuel cells, based on solid technology, convert hydrogen or hydrogen-rich fuels into electrical energy, with potential applications in stationary power generation. Conversely, electrolysers electricity chemical thereby offering the to store from transient resources, such as wind turbines and other renewable technologies. For displace conventional conversion devices marketplace, reliability must be improved, product lifecycles extended, unit costs reduced. Mathematical models can provide qualitative quantitative insight physical phenomena performance, over a range of length time scales. The purpose this paper is reader summary state-of-the art cell models. These from: simple methods lumped parameters little no kinetics detailed, time-dependent, three-dimensional solutions electric field potentials, complex fully-comprehensive equations motion effective transport properties. Many mathematical have, past, been inaccurate property values obtained literature, well over-simplistic schemes compute values. It important aware underlying experimental available parameterise models, validate results. In article, state-of-the-art techniques measuring kinetic, properties also described. Methods electrochemical impedance spectroscopy allow fundamental physicochemical obtained. addition, may using micro-scale computer simulations digital reconstruction X-ray tomography/focussed ion beam scanning electron microscopy, percolation theory. cornerstone model validation, namely polarisation current-voltage diagram, provides necessary, but insufficient information substantiate detailed calculations. results experiments which precisely mimic details conditions scarce, it fair say there gap between two activities. review introduce current analysis techniques, tutorial fashion, not only numerical experimental, emphasise cross-linkages techniques.

Investigation the performance of solid oxide fuel cells and the role of nanotechnology in its construction
Nanotechnology is well used in the development and performance improvement of solid oxide fuel cells (SOFCs). The high operating temperature of SOFCs (700-900 ° C) has led to serious shortcomings in their overall performance and durability. Hence, the high operating temperature has been reduced to the average temperature range of approximately 44-700 Celsius, which has improved performance and ...

متن کامل3D geometrical characterization and modelling of solid oxide cells electrodes microstructure by image analysis
A strong correlation exists between the performance of Solid Oxide Cells (SOCs), working either in fuel cell or electrolysis mode, and their electrodes microstructure. However, the basic relationships between the three-dimensional characteristics of the microstructure and the electrode properties are not still precisely understood. Thus, several studies have been recently proposed in an attempt...
