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 ...
Thermodynamic analysis, of a solid oxide fuel cell system fuelled by ethanol
(2001)
In the present study, a detailed thermodynamic analysis has been carried out in order to provide useful information concerning ethanol utilization as alternative fuel in solid oxide fuel cells (SOFCs). by using different ...
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 ...
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 ...
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, ...
Performance comparison of low-temperature direct alcohol fuel cells with different anode catalysts
(2004)
Low-temperature polymer electrolyte membrane fuel cells directly fed by methanol and ethanol were investigated employing carbon supported Pt, PtSn and PtRu as anode catalysts, respectively. Employing Pt/C as anode catalyst, ...
