Bi- and tri-metallic Pt-based anode catalysts for direct ethanol fuel cells
(2004)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 alcohol fuel cells: Challenges and future trends
(2011)Among the most considered future alternative energy conversion systems are fuel cells. A fuel cell is an electrochemical device that continuously and directly converts chemical energy to electricity with the most common ... -
Direct ethanol fuel cell anode simulation model
(2006)The electrochemical behavior of a direct ethanol feed proton exchange membrane fuel cell (DEFC) operating under steady-state isothermal conditions at 1 atm at both anode and cathode sides is considered. A mathematical model ... -
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 ethanol solid oxide fuel cells: The case of PT anodes
(2005)The limitation of fossil fuels deposits and the detrimental effects of their combustion emissions on the environment make it necessary to develop alternative technologies, such as fuel cells and use the renewable and ... -
The effect of anode bed geometry on the hydraulic behaviour of PEM fuel cells
(2016)The influence of the anode bed geometry on the hydraulic behaviour of PEM fuel cells is assessed. Three basic geometrical patterns are studied, namely the interdigitated, the parallel and the serpentine ones, in their ... -
A facile route to achieve ultrafine Fe2O3 nanorods anchored on graphene oxide for application in lithium-ion battery
(2019)Ultrafine Fe2O3 nanorods anchored on graphene oxide (GO) are synthesized by a one-pot route under mild conditions in presence of KMnO4 and Ni foam. Ni foam is beneficial for the formation of Fe2O3 rather than FeOOH under ... -
Ion incorporation on the Zr2CS2 MXene monolayer towards better-performing rechargeable ion batteries
(2022)We study Li and, for the first time, K, Mg and Zn ion intercalation on the surface of the Zr2CS2 MXene monolayer, taking advantage of the fact that the S terminations lower the diffusion barrier of the ions. We find that ... -
Ordered mesoporous tungsten carbide/carbon composites promoted Pt catalyst with high activity and stability for methanol electrooxidation
(2014)The current anode materials used for direct methanol fuel cells (DMFCs) are expensive and not sufficiently durable for commercial development. One of the major challenges lies in the development of an inexpensive, efficient ... -
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 ...
