Exergetic potential of fuels: The case of a SOFC-based power plant
(2004)
The method of exergy analysis is presented for a SOFC power plant involving external steam reforming and fed by methane and ethanol. The optimal operation parameters of the integrated SOFC plant are specified after minimizing ...
Thermodynamic and economic analysis of a steam reformer-solid oxide fuel cell system fed by natural gas and ethanol
(2002)
In the present work, ethanol and methane are compared as candidate fuels for solid oxide fuel cells (SOFCs). The thermodynamic analysis of both alternatives was undertaken considering that a SOFC stack operates by being ...
Catalytic and electrocatalytic oxidation of ethanol over a La0.6Sr0.4Co0.8Fe0.2O3 perovskite-type catalyst
(2000)
The catalytic and electrocatalytic behavior of the perovskite-type La0.6Sr0.4Co0.8Fe0.2O3 catalyst was investigated during ethanol oxidation. Experiments were carried out at atmospheric pressure in a fully yttria-stabilized ...
Exergy analysis of an ethanol fuelled proton exchange membrane (PEM) fuel cell system for automobile applications
(2005)
An integrated ethanol fuelled proton exchange membrane fuel cell (PEMFC) power system was investigated following a second law exergy analysis. The system was assumed to have the typical design for automobile applications ...
High temperature electrochemical oxidation of ethanol over perovskite-type oxides
(2000)
Ethanol oxidation was investigated in a solid electrolyte electrochemical reactor using a perovskite-type oxide La0.6Sr0.2Co0.8Fe0.2O3 as anode. Experiments were conducted between 300-750 degreesC at atmospheric pressure ...
Performance comparison of low-temperature direct alcohol fuel cells with different anode catalysts
(2004)
Low-temperature polymer electrolyte membrane fuel cells directly fed by methanol and ethanol were investigated employing carbon supported Pt, PtSn and PtRu as anode catalysts, respectively. Employing Pt/C as anode catalyst, ...
The importance of the fuel choice on the efficiency of a solid oxide fuel cell system
(2003)
A simplified model has been formulated in order to easily and adequately determines the efficiency of a solid oxide fuel cell (SOFC) stack system, independently on the fuel choice. Simple analytical formulas for the ...
