Carbon-supported PdSn and Pd3Sn2 anodes for glucose electrooxidation in alkaline media
(2014)PdSn (20 wt.%) and Pd3Sn2 (20 wt.%) nanoparticles supported on Vulcan XC-72 carbon powders are prepared by a modified microwave-assisted polyol method and studied for the reaction of glucose electrooxidation in alkaline ... -
Direct ethanol PEM fuel cells: The case of platinum based anodes
(2005)PtSn/C catalysts were prepared by the direct decoration of Pt/C with Sn through a modified poly process. XRD results showed there existed obvious SnO2 in this catalyst, different from the PtSn/C prepared by co-precipitation, ... -
Direct methanol fuel cells: The effect of electrode fabrication procedure on MEAs structural properties and cell performance
(2005)In the present paper, the effect of electrode preparation procedure on the structural properties of membrane electrode assembly (MEA) and consequently on the performance of direct methanol fuel cells (DMFCs) was investigated. ... -
Low and non-platinum electrocatalysts for PEMFCs: Current status, challenges and prospects
(2012)Platinum-based nanomaterials are the most commonly adopted electrocatalysts for both anode and cathode reactions in polymer electrolyte membrane fuel cells (PEMFCs) fed with hydrogen or low molecular alcohols. However, the ... -
PtM/C (M = Sn, Ru, Pd, W) based anode direct ethanol-PEMFCs: Structural characteristics and cell performance
(2007)In the present work, the role of the structural characteristics of Pt-based catalysts on the single direct ethanol proton exchange membrane fuel cell (PEMFC) performance is examined. Several PtM/C (M = Sn, Ru, Pd, W) ... -
Synthesis gas production by steam reforming of ethanol
(2001)A two-layer fixed-bed catalytic reactor for syngas production by steam reforming of ethanol has been proposed. In the reactor, ethanol is first converted to a mixture of methane, carbon oxides and hydrogen over a Pd-based ... -
A thermodynamic analysis of hydrogen production via aqueous phase reforming of glycerol
(2015)The thermodynamic analysis of glycerol (C3H8O3) aqueous phase reforming (APR) has been performed following the Gibbs free energy minimization method. The effect of the operating parameters, i.e. water to glycerol mass ratio ...
