The invention relates to a method for the production of a proton exchange membrane for a fuel cell, consisting in: preparing a solution comprising at least one solvent representing between 5 and 75 wt.-%, advantageously between 5 and 50 wt.-%, in relation to the weight of the solution, and at least one superacid having a pKa of between -3 and -30 and representing between 25 and 95 wt.-%, advantageously between 50 and 95 wt.-% in relation to the weight of the solution; and impregnating a polymer membrane in said superacid solution for a period of less than one hour and at a temperature of between 25 and 90°C. |
