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 the MEA preparation procedure on both ethanol crossover and DEFC performance
(2005)
In the present work, the changes of Nafion((R))-115 membrane porosity in the presence of ethanol aqueous solutions of different concentrations were determined by weighing vacuum-dried and ethanol solution-equilibrated ...
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 ...
Pt-based anode catalysts for direct ethanol fuel cells
(2004)
In the present work, several carbon supported PtSn and PtSnRu catalysts were prepared with different atomic ratios and tested in direct ethanol fuel cells (DEFC) operated at lower temperature (T=90 degreesC). XRD and TEM ...
Direct ethanol PEM fuel cells: The case of platinum based anodes
(2005)
PtSn/C catalysts were prepared by the direct decoration of Pt/C with Sn through a modified poly process. XRD results showed there existed obvious SnO2 in this catalyst, different from the PtSn/C prepared by co-precipitation, ...
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 ...
Direct methanol fuel cells: Methanol crossover and its influence on single DMFC performance
(2004)
In the present investigation, the methanol crossover rate through Nafion((R))-115 membrane at different temperatures and different concentrations had been investigated in a fuel cell test apparatus by using gas chromatography ...
