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 ...
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 ...
Effect of pore morphology of mesoporous carbons on the electrocatalytic activity of Pt nanoparticles for fuel cell reactions
(2010)
In the present investigation, the role of the pore morphology of mesoporous carbons in the electrocatalytic activity of Pt nanoparticles for fuel cell reactions has been successfully revealed by adopting ordered mesoporous ...
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 ...
Preparation and characterization of a novel KOH activated graphite felt cathode for the electro-Fenton process
(2015)
In the present investigation, graphite felt (GF) activated by KOH at high temperature is adopted as the electro-Fenton cathode for degrading organic pollutants contained in the wastewater. Scanning electron microscopy ...
Degradation of perfluorinated sulfonic acid films: An in-situ infrared spectro-electrochemical study
(2009)
The in-situ Fourier transform infrared (FTIR) spectro-electrochemical method was used to evaluate the degradation mechanism of perfluorinated sulfonic acid (PFSA) polymer for the first time. The effect of H 2O 2 concentration ...
Ethanol/water mixture permeation through a Nafion (R) based membrane electrode assembly
(2007)
In the present work, the permeation behavior of ethanol/water mixtures through a Nafion((R))- 115 based membrane electrode assembly (MEA) has been investigated. The crossover measurements were carried out in a single fuel ...
Pt based anode catalysts for direct ethanol fuel cells
(2003)
In the present work several Pt-based anode catalysts supported on carbon XC-72R were prepared with a novel method and characterized by means of XRD, TEM and XPS analysis. It was found that all these catalysts are consisted ...
