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 ...
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 ...
High temperature electrochemical oxidation of ethanol over perovskite-type oxides
(2000)
Ethanol oxidation was investigated in a solid electrolyte electrochemical reactor using a perovskite-type oxide La0.6Sr0.2Co0.8Fe0.2O3 as anode. Experiments were conducted between 300-750 degreesC at atmospheric pressure ...
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, ...
Direct methanol fuel cells: The effect of electrode fabrication procedure on MEAs structural properties and cell performance
(2005)
In the present paper, the effect of electrode preparation procedure on the structural properties of membrane electrode assembly (MEA) and consequently on the performance of direct methanol fuel cells (DMFCs) was investigated. ...
