Abstract[English]
Dispersion According to the present invention there is provided a dispersion comprising: a solvent; and a radical scavenger dispersed in the solvent. The radical scavenger comprises particles and each particle comprises cerium, a metal (M) and oxygen, wherein the metal (M) is present in an oxidation state of +5. There is also provided an ion-conducting membrane, catalyst- coated ion-conducting membrane, membrane electrode assembly, electrochemical device, and associated methods of producing a dispersion.[French]
La dispersion selon la présente invention concerne une dispersion comprenant : un solvant ; et un piégeur de radicaux dispersé dans le solvant. Le piégeur de radicaux comprend des particules et chaque particule comprend du cérium, un métal (M) et de l'oxygène, le métal (M) étant présent dans un état d'oxydation de +5. L'invention concerne également une membrane conductrice d'ions, une membrane conductrice d'ions revêtue de catalyseur, un ensemble membrane-électrode, un dispositif électrochimique et des procédés associés de production d'une dispersion.
