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.
