Abstract Fuel cells hold great promise as a clean energy technology, yet challenges such material compatibility, manufacturing costs, and durability issues, particularly with noble metal-based electrocatalysts like platinum (Pt), hinder their widespread adoption. This review explores strategies to enhance fuel cell performance while minimizing focusing on developing efficient cost-effective catalysts supported by nanocarbon materials, carbon nanotubes, graphene, films, composites. The investigation delves into how these supports improve activity stability, leading superior characterized higher current density enhanced compared conventional Pt/C catalysts, specific focus proton-exchange membrane cells. Key topics covered include the role of in cells, various nanocarbon-based catalyst supports, Pt-containing alloys, non-Pt composites for electrolyte membranes corrosion protection. Notable findings importance heteroatom doping enhancing reactivity, effectiveness organic–inorganic composite proton exchange improving conductivity, potential amorphous film coatings conductive polymer-nanocarbon resistance. These advancements underscore ensuring reliability longevity components, thus contributing commercialization technology.

The symmetry of the valence and conduction bands in graphene carbon nanotubes allows for easy modification electronic structure, which is correlated with their electrocatalytic activity. Modifying structure sp2-bonded nanocarbons by substituting atoms electron donors/acceptors through covalent functionalization can facilitate heterogeneous transfer (HET), beneficial designing carbon-based, high-performance electrocatalysts. Based on Gerischer–Marcus model, we discuss how match density π-electron states (DOS) a nanocarbon electrode to redox potential species using hole doping. Along results, this article provides guidance properties specific electroactive analytes, oxygen reduction reaction (ORR), hydrogen evolution (HER), (OER).
