“…The most common method used to prepare metal nanoparticle catalyst on supports for fuel cell electrodes is a reduction method where the metal salts and the support material are mixed in a beaker. Subsequently, a reduction agent, for instance sodium borohydrate (NaBH 4 ) [153][154][155] or glycerol [156][157][158], is added drop wise to the solution to reduce the metal particles directly on the catalyst support. This traditional method has a disadvantage that it is difficult to scale up without losing the control of catalyst particle size and distribution.…”

“…Multi-metallic Pt based catalysts were studied on the electrooxidation of ethylene glycol (EG) in alkaline medium [51]. The addition of Bi to platinum caused a positive shift of the onset potential for EG oxidation by 70 mV but an increase of current density.…”

Direct alkaline alcohol fuel cells (DAAFCs) have attracted increasing interest over the past decade because of their favourable reaction kinetics in alkaline media, higher energy densities achievable and the easy handling of the liquid fuels. In this review, principles and mechanisms of DAAFCs in alcohol oxidation and oxygen reduction are discussed. Despite the high energy densities available during the oxidation of polycarbon alcohols they are difficult to oxidise. Apart from methanol, the complete oxidation of other polycarbon alcohols to CO 2 has not been achieved with current catalysts. Different types of catalysts, from conventional precious metal catalyst of Pt and Pt alloys to other lower cost Pd, Au and Ag metal catalysts are compared. Non precious metal catalysts, and lanthanum, strontium oxides and perovskite-type oxides are also discussed. Membranes like the ones used as polymer electrolytes and developed for DAAFCs are reviewed. Unlike conventional proton exchange membrane fuel cells, anion exchange membranes are used in present DAAFCs. Fuel cell performance with DAAFCs using different alcohols, catalysts and membranes, as well as operating parameters are summarised. In order to improve the power output of the DAAFCs, further developments in catalysts, membrane materials and fuel cell systems are essential. OPEN ACCESSEnergies 2010, 3 1500

“…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.…”

This paper and the associated presentation will describe the latest developments regarding alkaline anion-exchange membrane (AAEM) fuel cells at Surrey. The program of work conducted has been targeted at the materials development of both membranes and electrodes containing alkaline ionomers and as such has focused on H 2 /O 2 fuel cell testing. Radiation-grafted AAEMs can be made with fully hydrated thicknesses between 18 -80 µm with conductivities in water of up to 0.06 S cm -2 at 60°C. A peak power density of 230 mW cm geo -2 and a maximum current density at full discharge of 1.3 A cm geo -2 have been obtained in a H 2 /O 2 fuel cell at 50°C with a 18 µm AAEM and Toray carbon paper based electrodes (Pt/C(20%mass), 0.5 mg Pt cm geo -2 loading) that were treated with Surrey's first generation alkaline ionomer. A future priority is the development of the next generation alkaline ionomer.
