High-activity platinized-carbon anodes for methanol oxidation have been prepared. XPS investigation of the electrodes showed the presence of both Pt" and oxidized Pt species. The enhanced activity of these electrodes, compared with Pt black, can be explained in terms of the unusual surface propertie
In the present work, a detailed characterization of the electrochemical behavior of carbon supported PdePt electrocatalysts toward CO and methanol electrooxidation in direct methanol fuel cells is reported. Technical electrodes containing an ionomer in their catalyst layer were prepared for this pur
