(EN)

The present disclosure is directed to microparticles comprising carbon, wherein a plurality of nanoparticles are supported on the surface of the microparticle. The nanoparticles comprise at least one transition metal compound selected from the group consisting of transition metal carbides, transition metal nitrides, transition metal sulfides, transition metal phosphides, transition metal carbonitrides, transition metal sulfonitrides, transition metal carbosulfides, transition metal phosphocarbides, transition metal phosphonitrides, transition metal phosphosulfides, transition metal carbosulfonitrides, transition metal carbophosphonitrides, transition metal phosphosulfonitrides, transition metal carbophosphosulfonitrides, and interstitial derivatives thereof. The present disclosure is also directed to processes for preparing such microparticles and to polymer electrolyte membranes (PEMs) that comprise such microparticles, as well as to the use of such PEMs in fuel cells.
