Patent

CA 2513817

The invention relates to a conductive organic-inorganic hybrid material comprising a mineral phase in which walls define pores forming a structured mesoporous network with open porosity. The inventive material also comprises an oligomer or an organic polymer which is incorporated into the aforementioned walls and which is covalently linked to the mineral phase and, optionally, another phase inside the pores, comprising at least one surface active agent, whereby at least the mineral phase or the oligomer or the organic polymer have conductive functions. The invention also relates to a membrane and electrode comprising said material. The invention further relates to a fuel cell comprising at least one such membrane and/or at least one such electrode and to a method of preparing said material.

Matériau hybride organique-inorganique conducteur comprenant une phase minérale dans laquelle des murs délimitent des pores formant un réseau mésoporeux structuré à porosité ouverte ; ledit matériau comprenant en outre un oligomère ou un polymère organique intégré dans lesdits murs et lié par covalence à la phase minérale, et éventuellement une autre phase à l~intérieur des pores, constituée par au moins un agent tensioactif ; au moins un parmi la phase minérale et l~oligomère ou le polymère organique présentant des fonctions conductrices. Membrane et électrode comprenant ce matériau. Pile à combustible comprenant au moins une telle membrane et/ou au moins une telle électrode. Procédé de préparation dudit matériau.
