Abstract (en)
[origin: WO2009040365A1] The invention relates to a method for making a proton-conducting membrane for a fuel cell, that successively comprises: the step of irradiating a polymer matrix; the step of grafting the polymer matrix thus irradiated by a radical reaction with a first compound, that comprises contacting the irradiated polymer matrix with said first compound, wherein said compound includes at least one group capable of forming a covalent bond by radical reaction with said matrix, and includes at least one reactive group capable of reacting with a group of a second compound containing at least one proton-conducting acid group for forming a covalent bond; and the step of contacting the matrix thus grafted with the second compound, whereby a reaction occurs between the reactive groups from the first compound and the appropriate groups of the second compound.
