Direct ethanol fuel cells based on PtSn anodes: The effect of Sn content on the fuel cell performance
(2005)
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 ...
Direct methanol fuel cells: The influence of methanol on the reduction of oxygen over Pt/C catalysts with different particle sizes
(2005)
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 ...
