Promotion of Direct Methanol Electro-oxidation by Ru Terraces on Pt by using a Reversed Spillover Mechanism

Methanol Electro-Oxidation on Pt-Ru Alloy Nanoparticles Supported on Carbon Nanotubes

Carbon nanotubes (CNTs) have been investigated in recent years as a catalyst support for proton exchange membrane fuel cells. Improved catalyst activities were observed and attributed to metal-support interactions. We report a study on the kinetics of methanol electro-oxidation on CNT supported Pt-Ru alloy nanoparticles. Alloy catalysts with different compositions, Pt53Ru47/CNT, Pt69Ru31/CNT an...

Mixed phase Pt-Ru catalyst for direct methanol fuel cell anode by flame aerosol synthesis

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...

Evaluation of the activity of Pt–Ru electro catalysts based on LyFlex®Gas Diffusion Layer for the electro-oxidation of methanol

The gas diffusion layer (GDL) is vital to the performance and durability of direct methanol fuel cell (DMFC). The GDL plays an important role in water management, catalyst efficiency and conductivity of DMFC. The GDL consists of a carbon substrate that can either be woven or non-woven. The various substrates used to produce GDLs result in very different physical characteristics, particularly su...
