Magnetic Modification of Nano-structured Direct Methanol Fuel Cell Anode Catalysts

The anode electro-oxidation of methanol is central to the operation of Direct Methanol Fuel Cells (DMFC), which have the potential to become the fastest growing next generation mobile power sources. While Pt and Pt-based catalysts are known for their effectiveness in methanol activation, they are also most susceptible to catalyst poisoning by reaction intermediates such as CO. A second or even ...

High-performance alkaline direct methanol fuel cell using a nitrogen-postdoped anode.

A commercial PtRu/C catalyst postdoped with nitrogen demonstrates a significantly higher performance (~10-20% improvement) in the anode of an alkaline direct methanol fuel cell than an unmodified commercial PtRu/C catalyst control. The enhanced performance shown herein is attributed at least partially to the increased electrochemical surface area of the PtRu/C after postdoping with nitrogen.

Pt-Ru supported on double-walled carbon nanotubes as high-performance anode catalysts for direct methanol fuel cells.

Pt-Ru supported on carbon nanotubes (CNTs) (single-walled nanotubes, double-walled nanotubes (DWNTs), and multi-walled nanotubes) catalysts are prepared by an ethylene glycol reduction method. Pt-Ru nanoparticles with a diameter of 2-3 nm and narrow particle size distributions are uniformly deposited onto the CNTs. A simple and fast filtration method followed by a hot-press film transfer is emp...
