DURABLE HYBRID ELECTROCATALYSTS FOR FUEL CELLS

Electrocatalysts and methods of forming the same are provided. A hybrid electrocatalyst can be a combination of a platinum (Pt)-based catalyst and a carbon-based non-precious-metal catalyst using a single atom approach. A fuel cell electrocatalyst can include a nitrogen-doped carbon support and a plurality of atoms of both Pt and of a non-precious-metal catalyst dispersed in the support. The dispersed atoms can be isolated from each other within the support.
