Matsuoka et al. [8] tested ADAFCs formed by Pt-Ru/C as anode catalyst, Pt/C or Ag/C as cathode catalyst, and the AHA membrane by Tokuyama Co. The cells operated at 50 °C and were fuelled with four polyhydric alcohols and methanol for comparison. These alcohols (1 M) were dissolved in 1 M KOH aqueous solution. The maximum power densities were in the order of ethylene glycol > glycerol > methanol > erythritol > xylitol. The direct ethylene glycol fuel cell showed the highest power density. AlkaUne direct alcohol fuel cells using silver as a cathode catalyst showed good performance however, the open-circuit voltage of a cell with... [Pg.108]

Fuels cells are of interest both from energetic and environmental considerations. When methanol is fed directly to an anode, as in Direct Methanol Fuel Cells , electric power is generated, making the devices suitable for small and lightweight uses [53], Alternative fuels such as polyhydric alcohols like ethylene glycol and glycerol are much less volatile and toxic, on the one hand, and electrochemically oxidizable on the other [54]. Therefore, the electrochemical oxidation of various polyhydric alcohols has been investigated in acidic as well as in alkaline conditions. [Pg.231]

In recent decades, direct alcohol fuel cells (DAFCs) have been extensively studied and considered as possible power sources for portable electronic devices and vehicles in the near future. The application of methanol is limited due to its high volatility and toxicity, although it is relatively easily oxidized to CO2 and protons. So other short chain organic chemicals especially ethanol, ethylene glycol, propanol, and dimethyl... [Pg.309]

Fuel cells, due to their higher efficiency in the conversion of chemical into electrical energy vhth respect to thermo-mechanical cycles, are another major area of R D that has emerged in the last decade. Their effective use, ho vever, still requires an intense effort to develop ne v materials and catalysts. Many relevant contributions from catalysis (increase in efficiency of the chemical to electrical energy conversion and the stability of operations, reduce costs of electrocatalysts) are necessary to make a step for vard in the application of fuel cells out of niche areas. This objective also requires the development of efficient fuel cells fuelled directly vith non-toxic liquid chemicals (ethanol, in particular, but also other chemicals such as ethylene glycol are possible). Together vith improvement in other fuel cell components (membranes, in particular), ethanol direct fuel cells require the development of ne v more active and stable electrocatalysts. [Pg.10]

The growth of interest in DMFC and DEFC seems to have reached a steady state during the last years with almost a factor 5 more works on methanol respect to ethanol. It can be also observed an incipient interest for ethylene glycol and propanol as a direct fuel in PEM fuel cell since 2000, and a small but raising number of studies exploring glycerol as a new liquid fuel since 5 years ago. [Pg.8]

Reviews on DEFC become available since 2006, describing the state of the art of catalysts for ethanol oxidation [31, 76, 77], while more recent works focused oti alkaline DEFC [78-80]. A comprehensive review on alkaline direct alcohol fuel cells was recently published by one of us [30] over viewing catalysts, membranes and cell performance of ADAFC fuelled with methanol, ethanol, and ethylene glycol. [Pg.26]

Considering all the types of Direct Alcohol Fuel Cells (DAFC) currently in development, that using methanol (DMFC) is closer to massive commercialization. DMFC exhibits higher current and power densities than fuel cells using ethanol, ethylene glycol, etc., mainly due to the difficulty for breaking the C-C bonds of higher alcohols. For this reason this Chapter will be mainly devoted to review the applications of DMFC. [Pg.321]

Abstract The faster kinetics of the alcohol oxidation reaction in alkaline direct alcohol fuel cells (ADAFCs), opening up the possibility of using less expensive metal catalysts, as silver, nickel, and palladium, makes the alkaline direct alcohol fuel cell a potentially low-cost technology compared to acid direct alcohol fuel cell technology, which employs platinum catalysts. In this work an overview of catalysts for ADAFCs, and of testing of ADAFCs, fuelled with methanol, ethanol, and ethylene glycol, formed by these materials, is presented. [Pg.89]

In this work an overview of anode catalysts for alkaline direct alcohol fuel cells, and reports of the testing of these materials in alkaline direct alcohol fuel cells fuelled with Ci (methanol) and C2 (ethanol and ethylene glycol) alcohols, is presented. [Pg.90]

In direct alcohol fuels cells (DAFCs), some simple organic molecules such as methanol, ethanol, formic acid, and ethylene glycol are used as alternative fuels. Besides the slow kinetics of ORR in the cathode, the slow alcohol oxidation reaction on Pt is another major contribution to low DAFC performance. [Pg.751]
