Improved platinum‐nickel nanoparticles with dopamine‐derived carbon shells for proton exchange membrane fuel cells

Summary Using platinum‐based alloy nanocatalysts with other transition metals has the advantages of enhancing the oxygen reduction reaction (ORR) activity and reducing the platinum usage. However, there are many challenges to using nanocatalysts, including their instability, which hinder their pract...
