Recent developments of nanocarbon based supports for PEMFCs electrocatalysts

Nanocarbons, widely and commonly used as supports for supported Pt-based electrocatalysts in PEMFCs, play a significant role Pt dispersion accessibility, further determining their corresponding electrocatalytic performance. This paper provides an overview of the nanoarchitectures surface physicochemical properties nanocarbons affecting electrocatalyst performance, with emphasis on both physical characteristics, including pore structure, chemical properties, heteroatom doping functional carbon-based supports. review discusses recent progress nanocarbon supports, guides future development direction PEMFC our own viewpoints research design PEMFCs catalysts, advancing commercialization PEMFCs.
