A High Activity, Low-Cost Catalyst Comprising an Inexpensive Core and a Thin Precious Metal Shell for Fuel Cells, and a Method for Making the Same

Invention SummaryThis invention describes a catalyst with a (1 nm) shell of a precious metal (e.g., platinum) on a nanoparticle core of inert material. The shell is sufficiently thin to achieve a large surface area per unit mass of the metal, yet sufficiently thick so that the material behaves like bulk material. The invention also teaches a me...
