Researchers Find Way to Improve Fuel Cell Catalysts
The gold clusters were found to stabilise the platinum during the oxidisation process and prevent losses to the surface area.
Scientists claim to have demonstrated a new technique
which allows them to improve the stability of platinum fuel cell
electro-catalysts using gold clusters.
Research published by New
York-based scientists in the journal Science claims that platinum nanoparticles
can be modified with gold clusters, stabilising the catalyst against dissolution
under potential cycling regimes.
