Nitrogen Plasma Modified Carbons for PEMFC with Increased Interaction with Catalyst and Ionomer

Abstract : Vulcan XC72 carbon black, conventionally used as electrocatalyst support in proton exchange membrane fuel cells, was doped with nitrogen functionalities by exposing it to nitrogen plasma, and the effect on its morphology, structure and texture and surface properties was investigated. In particular, the strength of the interaction between the modified carbon and Nafion® ionomer was evaluated by isothermal titration calorimetry, and an enhanced exothermic effect was observed on increasing the amount of nitrogen at the Vulcan surface. The undoped and nitrogen-doped carbon blacks were catalysed with Pt nanoparticles, and the resulting materials were characterised for their electrocatalytic properties towards the oxygen reduction reaction. The electrocatalyst using nitrogen-doped supports are characterised by higher activity and stability, which is attributed to a strong Pt-support interaction promoted by the presence of the heteroatoms.
