Ethanol/water mixture permeation behavior through membrane electrode assembly (MEA) in PEMFC
(2005)
Direct ethanol fuel cells (DEFCs) have been paid more and more attention in recent years due to the following advantages of ethanol: low toxicity, renewability and easy production by the fermentation of agricultural products ...
Benzene electro-oxidation in a PEMFC for phenol and electricity cogeneration
(2005)
In the present investigation, the electrochemically-assisted oxidation of benzene in a H2-O2 proton exchange membrane fuel cell (PEMFC), for electricity and phenol cogeneration is studied. Experiments were carried out in ...
Recent advances in direct alcohol PEMFCS
(2005)
Direct alcohol proton exchange membrane fuel cells (DAFCs) have been under active and extensive investigation worldwide due to the easy handle of the liquid fuels, which can be directly fed to the anode compartment and ...
The effect of methanol and ethanol cross-over on the performance of PtRu/C-based anode DAFCs
(2005)
In the present work, the cross-over rates of methanol and ethanol, respectively, through Nafion®-115 membranes at different temperatures and different concentrations have been measured and compared. The changes of Nafion®-115 ...
An exergetic analysis of an ethanol FED SOFC-GT hybrid system
(2009)
A parametric analysis optimization and comparison of the exergetic efficiency (2nd law) of two different Solid Oxide Fuel Cell based power plants (SOFC-GT and SOFC) is carried out in the present work. The fuel with which ...
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 ...
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 ...
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 ...
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 ...
