| description | The invention relates to a process for preparing proton-conducting clay particles, successively comprising the following steps: a) a step of activating a clay powder, comprising a step in which the said powder is subjected to a gas plasma; b) a grafting step comprising a step of placing the activated powder obtained from step a) in contact with a solution comprising at least one compound comprising at least one group chosen from -PO3H2, -CO2H and -SO3H and salts thereof and comprising at least one group capable of grafting onto the surface of the said powder. Use of these particles for the manufacture of fuel cell membranes. |
