Shaping platinum into ultrafine jagged nanowires and using it as a catalyst in hydrogen fuel cells would dramatically increase efficiency, lower cost. An international team including a CNR-ICCOM researcher develops a method that allows a 50-fold reduction in the amount of platinum. Jagged platinum nanowires are obtained by removing nickel from Pt-Ni regular alloy nanowires. […]

Thanks to innovative anode electrocatalysts based on nanostructured palladium, the first entirely platinum-free fuel cells have been created that release a power density greater than 500 mW cm-2. Their use could revive hydrogen technology for cars and portable energy generators with “zero emissions” of pollutants. The research was coordinated by ICCOM-Cnr of Florence. A fuel […]
