Anodic Oxidation of Polyhydric Alcohols on a Pt Electrode in Alkaline Solution

Investigations into the ex situ methanol, ethanol and ethylene glycol permeabilities of alkaline polymer electrolyte membranes

“…Notwithstanding this, the V OCV 's for the AAEMs with ethylene glycol compared well with the value obtained for Nafion; this is in line with the previous reports of electrokinetically facile EGOR in high pH media [12].…”

“…Initial indications, from a fuel cell study of a commercial AAEM (Morgane ® ADP, Solvay S.A., Belgium), suggest AAEMs exhibit reduced methanol permeability compared to Nafion [8]. Liquid methanol [9,10] and ethylene glycol [4,11] [12]. Ethanol (8.0 kW h dm -3 ) was also selected for evaluation in this study as it is a representative carbon-neutral biofuel.…”

Membrane and Electrode Materials for Alkaline Membrane Fuel Cells

“…Pd based anode catalysts appear promising for alcohol oxidation (31). Ethylene glycol is especially active towards electrooxidation in alkaline environments (21,22,32); ethylene glycol contains a C-C bond but, unlike with ethanol, the C/O ratio = 1 with each carbon atom bound to an oxygen atom. Most of these prior studies involved the addition of metal hydroxide to the alcohol fuel supply.…”

Ethylene Glycol Electro-Oxidation on Platinum-Free Surfaces: How the Composition of PdRuRh Surfaces Influences the Catalysis

“…In this subject, over recent years ethylene glycol (EG) has attracted increasing attention, as a possible candidate for use in direct alcohol fuel cells (DAFC) once it is a biorenewable, 1 highly soluble molecule. 2,3 Moreover, its low degree of toxicity, low flammability, high melting point, high energy density, high reactivity and high theoretical energy efficiency are characteristics that qualify it as a candidate for DAFC. [2][3][4] EG is an alcohol similar to ethanol (because it possesses a C−C bond in its structure), and is also similar to glycerol, once each carbon have a hydroxyl group attached to it.…”

[2][3][4] EG is an alcohol similar to ethanol (because it possesses a C−C bond in its structure), and is also similar to glycerol, once each carbon have a hydroxyl group attached to it. Thus, the study of its electro-oxidation can provide important information that could be applied to other alcohols of strategic interest in electrocatalysis.…”
