Selectivity of Direct Methanol Fuel Cell Membranes [PDF]

open access: yesMembranes, 2015
Sulfonic acid-functionalized polymer electrolyte membranes alternative to Nafion® were developed. These were hydrocarbon systems, such as blend sulfonated polyetheretherketone (s-PEEK), new generation perfluorosulfonic acid (PFSA) systems, and composite zirconium phosphate–PFSA polymers. The membranes varied in terms of composition, equivalent weight,

Long Term Performance Study of a Direct Methanol Fuel Cell Fed with Alcohol Blends

open access: yesEnergies, 2013
The use of alcohol blends in direct alcohol fuel cells may be a more environmentally friendly and less toxic alternative to the use of methanol alone in direct methanol fuel cells. This paper assesses the behaviour of a direct methanol fuel cell fed with

Materializing efficient methanol oxidation via electron delocalization in nickel hydroxide nanoribbon

open access: yesNature Communications, 2020
Development of suitable methanol oxidation reaction catalysts for direct methanol fuel cells is challenging due to sluggish kinetics. Herein, authors show that four-coordinate nickel atoms form charge-transfer orbitals near the Fermi energy level ...

Direct Methanol Fuel Cells

open access: yesPlatinum Metals Review, 1996
The direct methanol fuel cell (DMFC) has been considered as the ideal fuel cell system since it produces electric power by the direct conversion of the methanol fuel at the fuel cell anode. This is more attractive than the conventional hydrogen fuelled cells, particularly for transportation applications, which rely on bulky and often unresponsive ...

Mixtures of methanol and 2-propanol as a potential fuel for direct alcohol fuel cells [PDF]

open access: yesJournal of the Serbian Chemical Society, 2007
The electrochemical oxidation of methanol, 2-propanol, and their mixtures was investigated on a Pt/C thin film electrode in acid solution. It was confirmed that the oxidation of 2-propanol commences at less positive potentials than that of methanol and ...
