Simulation of the operation of a direct ethanol fuel cell anode
(2005)
Direct ethanol fuel cells (DEFCs) have motivated more and more interest in recent years due to the intrinsic advantages of ethanol such as its low toxicity, renewability, and its easy production in great quantity by the ...
Bi- and tri-metallic Pt-based anode catalysts for direct ethanol fuel cells
(2004)
In the present work, several Pt-based anode catalysts supported on activated carbon XC-72R were prepared by using a novel method, characterized and tested. XRD analysis and TEM images indicated that all of anode catalysts ...
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 ...
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 ...
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 ...
