Electricity from ethanol fed SOFCs: the expectations for sustainable development and technological benefits
Douvartzides, S. L.; Coutelieris, F. A.; Demin, A. K.; Tsiakaras, P. E. (2004)Based on a thermodynamic and economic analysis presented in the first part of this paper, ethanol is considered as an alternative fuel with suitable characteristics for electricity generation in SOFCs. Ethanol fed steam ... -
Electrochemically promoted catalysis: The case of ethanol oxidation over Pt
Douvartzides, S. L.; Tsiakaras, P. E. (2002)Ethanol oxidation was investigated over polycrystalline Pt films deposited on 8 mol% Y2O3-stabilized-ZrO2 (YSZ) in the temperature range of 300-350degreesC. It was found that electrochemical supply of oxygen anions (O2-) ... -
Forced convectional heat transfer in solid oxide fuel cells: An analytical treatment
Coutelieris, F. A.; Demin, A. K.; Douvartzides, S. L.; Tsiakaras, P. E. (2003)The heat transfer within a fuel cell at steady state conditions is considered here for one dimensional geometry. Analytical solution for the heat transfer equation accompanied by the appropriate boundary conditions is ... -

Heat transfer phenomena in a solid oxide fuel cell: An analytical approach
Couteheris, F. A.; Douvartzides, S. L.; Tsiakaras, P. E. (2005)The steady-state heat transfer problem within a fuel cell is considered here. The original 2-D problem is defined while an averaging technique is used in order to reduce its dimensions to one. The full heat transfer equations ... -
On the systematic optimization of ethanol fed SOFC-based electricity generating systems in terms of energy and exergy
Douvartzides, S. L.; Coutelieris, F. A.; Tsiakaras, P. E. (2003)An energy-exergy analysis was undertaken in order to optimize the operational conditions of a SOFC-based power plant fueled by ethanol. A certain plant configuration was contemplated, equipped with an external steam reformer, ... -
The oxidation of ethanol over Pt catalyst-electrodes deposited on ZrO2 (8 mol% Y2O3)
Tsiakaras, P. E.; Douvartzides, S. L.; Demin, A. K.; Sobyanin, V. A. (2002)The reaction of ethanol oxidation has been examined over a Pt polycrystalline film deposited on an yttria-stabilized zirconia (YSZ) electrochemical reactor. Experiments were carried out between 300 and 350 degreesC at ...
