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 ... -
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 ... -
Thermodynamic and economic analysis of a steam reformer-solid oxide fuel cell system fed by natural gas and ethanol
(2002)In the present work, ethanol and methane are compared as candidate fuels for solid oxide fuel cells (SOFCs). The thermodynamic analysis of both alternatives was undertaken considering that a SOFC stack operates by being ... -
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 ...
