By a News Reporter-Staff News Editor at Energy Weekly News -- Research findings on Hydrogen Energy are discussed in a new report. According to news reporting originating from Orsay, France, by VerticalNews correspondents, research stated, "Plasma-assisted deposition of platinum and platinum-palladium nano-particles at the surface of carbonaceous electronic carriers for application in proton-exchange membrane (PEM) electrochemical cells has been carried out using a conventional DC magnetron sputtering system. Different types of carrier have been used for that purpose: carbon powder (Vulcan XC-72), carbon nanotubes and carbon nano-fibers."
Our news editors obtained a quote from the research from the University of Paris, "The interest of initial chemical pretreatment or metallization of the electronic carrier to improve surface adhesion of catalyst nano-particles has been analyzed. Nanostructured catalytic powders thus obtained have been analyzed and characterized using TGA, SEM, TEM, XRD, XRF and cyclic voltammetry. The electrochemical performances of Pt/C and Pt-Pd/C electrodes have been measured in single-cell PEM fuel cell (PEMFC), water electrolyzer (PEMWE) and unitized regenerative fuel cell (URFC). Results show a high active surface area (up to 44 m(2) g(-1)) and high electrochemical activity for a number of synthesized samples."
According to the news editors, the research concluded: "A qualitative correlation has been established between sputtering parameters, type of carbon carrier and performances as electrocatalyst."
