Beschreibung
Zusammenfassung:	The invention relates to proton-conducting composites comprising a polymer matrix within which inorganic particles are dispersed, grafted to the surface of which particles are polymers comprising repeat units that comprise at least one acid proton-exchange group, optionally in the form of salts, or a precursor group of said acid group, said particles being chosen from particles of zeolites, of zirconium phosphates or phosphonates, or of oxides. Application to the field of fuel cells. L' invention a trait à des matériaux composites conducteurs de protons comprenant une matrice polymère au sein de laquelle sont dispersées des particules inorganiques, à la surface desquelles sont greffés des polymères comprenant des unités répétitives comprenant au moins un groupe acide échangeur de protons, éventuellement sous forme de sels, ou un groupe précurseur dudit groupe acide, lesdites particules étant choisies parmi les particules de zéolithes, de phosphates ou phosphonates de zirconium, d'oxydes. Application au domaine des piles à combustible.
