Claim Text:
1. Method for preparing platinum particles being functionalized by polymers comprising at least one repeating unit bearing at least one proton-conducting group and being covalently bonded to a carbon material, said method comprising the following consecutive steps: a) a step of contacting platinum particles with a compound that is an initiator for ATRP polymerization, which compound comprising a disulfide group —S—S— forming a bridge between two portions of said compound, said two portions being identical and comprising a phenyl group bearing an amide group —NH—CO—R b) a step of contacting said particles obtained in a) with at least one monomer meeting the following formula (II): in which: —Z corresponds to a phenyl group; and —E corresponds to a proton-conducting group, whereby there is polymerization of said monomer from the above-mentioned radicals.
