... is to convert it to useful products. This could be achieved via the electrochemical reduction of CO 2 using renewable electricity. Methanol (CH 3 OH), a valuable fuel and feedstock, is one of the CO 2 electroreduction products. However, its formation, thus far, has been plagued by the inadequacy of functional...

... manuscript received August 12, 2013; published online December 27, 2013. Assoc. Editor: Umberto Desideri. 08 02 2013 12 08 2013 High temperature direct methanol fuel cells (DMFCs) using polybenzimidazole (PBI) membranes could improve the energy density of portable power sources...

... some oxygenic functional groups. The activity of the composite catalysts for methanol electro-oxidation was investigated by using cyclic votammogram and chronoamperometry in acid media. The results indicated that modified mesoporous carbon can improve the catalytic ability of Pt catalyst for methanol...

.... Editor: Jacob Brouwer. 07 03 2011 05 10 2012 A steady-state, isothermal, one-dimensional model of a direct methanol proton exchange membrane fuel cell (PEMFC), with a polybenzimidazole (PBI) membrane, was developed. The electrode kinetics were represented by the Butler–Volmer...

... online May 7, 2013. Editor: Nigel M. Sammes. 07 10 2012 27 01 2013 The operation of a direct methanol fuel cell with an internal combustion engine in a hybrid system is investigated in terms of fuel efficiency. The following work shows a potential for fuel saving because the engine's...

...M. Mamlouk; K. Scott; N. Hidayati A study of a vapor feed DMFC using PBI loaded with phosphoric acid is reported. The anode catalyst was a Pt-Ru alloy and the cathode Pt, both supported on carbon black. Performance of the fuel cell with low methanol concentrations is reported and in situ...

... such as biogas, prereformed methanol, ethanol, and natural gas. The effects of fuel inlet composition and temperature are studied in terms of temperature distribution, molar fraction distribution, and reforming reaction rates within a singe cell for an intermediate temperature solid oxide fuel cell...

... as the reducing agent based on the empirical model. Deviations from the model were found when hydrazine was used as the reducing agent due to the formation of solution phase ruthenium complexes with hydrazine. 08 12 2008 23 07 2009 08 04 2010 08 04 2010 catalysts direct methanol fuel...

... process of polyvinyl alcohol sacrificial layer. A micromethanol reformer was fabricated using a typical lithography procedure including catalyst coating and patterning process. Typical methanol conversion was higher than the conventional packed bed reactor. An overview of prepared Cu ∕ Zn O...

...A. Verma; A. K. Jha; S. Basu The performance of an alkaline fuel cell (AFC) is investigated using three different fuels, e.g., methanol, ethanol, and sodium borohydride. Pt ∕ C ∕ Ni was used as anode, whereas Mn O 2 ∕ C ∕ Ni was used as standard (Electro-Chem-Technic, UK) cathode for all the fuels...
