Bifunctional anode catalysts for direct methanol fuel cells

Using the binding energy of OH* and CO* on close-packed surfaces as reactivity descriptors, we screen bulk and surface alloy catalysts for methanol electro-oxidation activity. Using these two descriptors, we illustrate that a good methanol electro-oxidation catalyst must have three key properties: (1) the ability to activate methanol, (2) the ability to activate water, and (3) the ability to re...

Methanol electro-oxidation on platinum modified tungsten carbides in direct methanol fuel cells: a DFT study.

In exploration of low-cost electrocatalysts for direct methanol fuel cells (DMFCs), Pt modified tungsten carbide (WC) materials are found to be great potential candidates for decreasing Pt usage whilst exhibiting satisfactory reactivity. In this work, the mechanisms, onset potentials and activity for electrooxidation of methanol were studied on a series of Pt-modified WC catalysts where the bar...

Support Effects on Palladium Catalysts for Methanol Fuel Applications

Methanol, formaldehyde, carbon monoxide, and propylene conversion were examined in a laboratory flow reactor over three base-metal containing alumina-supported palladium (Pd) catalysts in addition to Pd on y-alumina catalyst. The base metals were cerium, barium, and a combination of the two. Experiments were performed to determine the effect of air to fuel ratio on lightoff temperatures of vari...

Liquid methanol concentration sensors for direct methanol fuel cells

Liquid-fed direct methanol fuel cells (DMFCs) are one of the most promising candidates for portable power electronics and automotive pplications due to their potentially high-energy density, simple storage, and distribution of the fuel. The concentration of methanol in the fuel irculation loop of a DMFC system is an important operating parameter, because it determines the electrical performance...
