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 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 ...
