Bi- and tri-metallic Pt-based anode catalysts for direct ethanol fuel cells
In the present work, several Pt-based anode catalysts supported on activated carbon XC-72R were prepared by using a novel method, characterized and tested. XRD analysis and TEM images indicated that all of anode catalysts ...
Direct ethanol fuel cells based on PtSn anodes: The effect of Sn content on the fuel cell performance
In the present work, several carbon supported PtSn catalysts with different Pt/Sn atomic ratios were synthesized and characterized by X-ray diffraction (XRD), Transmission electron microscopy (TEM) and X-ray photoelectron ...
Pt-based anode catalysts for direct ethanol fuel cells
In the present work, several carbon supported PtSn and PtSnRu catalysts were prepared with different atomic ratios and tested in direct ethanol fuel cells (DEFC) operated at lower temperature (T=90 degreesC). XRD and TEM ...
Performance comparison of low-temperature direct alcohol fuel cells with different anode catalysts
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: Methanol crossover and its influence on single DMFC performance
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 ...
Direct methanol fuel cells: The influence of methanol on the reduction of oxygen over Pt/C catalysts with different particle sizes
Two Pt/C catalysts with different particle sizes (Pt/C: 2.5 nm, Pt/C-700Ar: 5.1 nm) were investigated by applying a half-cell configuration - rotating disk electrode (RDE) technique in H2SO4 aqueous solutions in the absence ...
