As an alternative or supplement to small batteries, the much-anticipated micro-direct methanol fuel cell ( DMFC) faces several key technical issues such as methanol crossover, reactant delivery, and byproduct release. This paper addresses two of the issues, removal of CO2 bubbles and delivery ofmethanol fuel, in a non-prohibitiveway for systemminiaturization. A recently reported bubble-driven p...

Ethanol is receiving great interest as an alternative fuel. Methanol is another alcohol fuel that could serve as a replacement for gasoline. Although it is currently receiving much less attention, it has the potential to play an important role. Like ethanol, methanol also has the advantage of being a liquid fuel and it can be produced from gasification of a variety of feedstocks using well esta...

Using NPT and NVT molecular dynamics simulation techniques, we have simulated an atomistic model of solvated Nafion in the lithium salt form, with the following three main objectives: (i) to obtain details on the local environment of the lithium cations and to assess the solvent effect on their binding, (ii) to investigate the translational and rotational motion of solvent molecules (water and ...

in this study, a sodalite nanozeolite was synthesized and characterized by x-ray diffraction (xrd) and scanning electronic microscopy (sem). following the morphology evolution of the sodalite nanozeolite in the sem images illustrates the formation of the spherical particle with a size between 60 and 80 nm. then, carbon paste electrode (cpe) was modified by sodalite nanozeolite and ni2+ ions. th...

The methanol oxidation reaction has been the subject of a large number of studies in the past.[1, 2] Early work revealed a complex reaction mechanism,[3–6] indicating the electrocatalysis of methanol oxidation as the most difficult task in the realization of a direct methanol fuel cell (DMFC). Several metal catalysts were proposed for the reaction, most of them based on modifications of Pt with...

The Front Cover shows that nanoengineering is a breakthrough way to look at the electrocatalysis field under different perspective. In their Research Article, M. Aurélio Suller Garcia, T. Silva Rodrigues and co-workers provided design of hollow AgPt-based electrocatalyst with improved resistance methanol for Direct Methanol Fuel Cells applications. After immobilization onto SiO2, nanostructures...

Current catalysts for the alcohol oxidation in fuel cells (typically noble metals-based) are susceptible to poisoning with intermediates like CO. Hence we decided to find superseded catalysts for methanol oxidation based on incorporation of mixed oxides. In this research, a nano-size perovskite SrFeO3-δ (SrFeO3<su...
