Abstract
A fuel cell catalyst material includes metal catalyst particles formed of a metal material and a carbon-based coating composition at least partially coating at least some of the metal catalyst particles. The carbon-based coating composition includes a carbon network. The carbon-based coating composition is doped with a dopant. The carbon-based coating composition includes a number of defects formed by one or more vacated carbon atoms in the carbon network. The carbon-based coating composition is made from a non-aromatic carbon molecule.
