Synthesis gas production by steam reforming of ethanol
(2001)
A two-layer fixed-bed catalytic reactor for syngas production by steam reforming of ethanol has been proposed. In the reactor, ethanol is first converted to a mixture of methane, carbon oxides and hydrogen over a Pd-based ...
Direct ethanol fuel cells based on PtSn anodes: The effect of Sn content on the fuel cell performance
(2005)
In the present work, several carbon supported PtSn catalysts with different Pt/Sn atomic ratios were synthesized and characterized by X-ray diffraction (XRD), Transmission electron microscopy (TEM) and X-ray photoelectron ...
Bioethanol steam reforming over Pt and Ag in an electrochemical CSTR reactor
(2005)
The environmental problems caused by the intensive use of fossil fuels-as well as their limited availability- are increasingly demanding a more rational use of our energy resources. Among the various fuels which can be ...
Exergy analysis of a solid oxide fuel cell power plant fed by either ethanol or methane
(2004)
The method of exergy analysis is presented for a solid oxide fuel cell (SOFC) power plant involving external steam reforming and fed by methane and ethanol. The parameters for optimal operation of the integrated SOFC plant ...
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 ...
Ethanol crossover phenomena and its influence on the performance of DEFC
(2005)
In the present work, Nafion (R) membrane porosity changes were determined in aqueous ethanol solutions with different concentrations by weighing vacuum-dried and ethanol aqueous solution equilibrated membranes at room ...
Recent progress in direct ethanol proton exchange membrane fuel cells (DE-PEMFCs)
(2006)
Direct ethanol fuel cells (DEFCs) belong to the family of proton exchange membrane fuel cells (PEMFCs), in which ethanol is directly used as the fuel. In the present work, the main aspects related to DEFCs such as ...
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 ...
