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 ... -
Pt based anode catalysts for direct ethanol fuel cells
(2003)In the present work several Pt-based anode catalysts supported on carbon XC-72R were prepared with a novel method and characterized by means of XRD, TEM and XPS analysis. It was found that all these catalysts are consisted ... -
Simulation of the operation of a direct ethanol fuel cell anode
(2005)Direct ethanol fuel cells (DEFCs) have motivated more and more interest in recent years due to the intrinsic advantages of ethanol such as its low toxicity, renewability, and its easy production in great quantity by the ... -
Study of the operational parameters effect on a direct ethanol PEM fuel cell performance by the aid on a mathematical model
(2011)In the present work, a model-based parametric analysis of the performance of a direct ethanol polymer electrolyte membrane fuel cell (DE-PEMFC) is conducted with the purpose to investigate the effect of several parameters ... -
Study of the products distribution during a direct ethanol PEM fuel cell operation
(2011)In the present work the effect of both cell discharge current and operating temperature on (a) the ethanol conversion, (b) the reaction products distribution and (c) the reaction yield towards each released product, during ... -
Two-step sequence for synthesis of efficient PtSn@Rh/C catalyst for oxidizing ethanol and intermediate products
(2012)PtSn@Rh/C-HT catalysts were designed and synthesized by a two-step sequence synthesis: Rh was firstly deposited on the carbon support and then PtSn through microwave assisted polyol method, followed by the heat treatment ... -
Understanding the electrocatalytic activity of PtxSny in direct ethanol fuel cells
(2011)In the present work, the activity of PtxSny/C catalysts towards ethanol, acetaldehyde and acetic acid electrooxidation reactions is investigated for each one separately by means of cyclic voltammetry. To this purpose, a ...
