Carbon-supported PdSn and Pd3Sn2 anodes for glucose electrooxidation in alkaline media
(2014)PdSn (20 wt.%) and Pd3Sn2 (20 wt.%) nanoparticles supported on Vulcan XC-72 carbon powders are prepared by a modified microwave-assisted polyol method and studied for the reaction of glucose electrooxidation in alkaline ... -
The effect of the parasitic current on the direct ethanol PEM fuel cell operation
(2008)In the present work the effect of the parasitic or leakage current, I, which is the result of the ethanol crossover through the polymer electrolyte membrane (PEM) from the anode to the cathode side of the cell, on both the ... -
Ethanol crossover and direct ethanol PEM fuel cell performance modeling and experimental validation
(2006)In the present work, a one-dimension, steady-state and single phase model is developed with the purpose of describing the mass transport within a PtRu/Nafion (R)-115/Pt membrane-electrode assembly and the performance of a ... -
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 ... -
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 ...
