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, ...
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. ...
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 ...
