## Abstract Zirconium phosphate (ZrP) was incorporated in preformed Nafion 117 membranes by exchange of the ionomer protons with zirconium cationic species and subsequent treatment with phosphoric acid. Reiteration of these treatments under the same reaction conditions allowed to obtain membranes w
## Abstract Nafion–zirconium phosphate (ZrP) composite membranes, containing 20 to 40 wt.‐% ZrP were treated with aqueous solutions of meta‐sulphophenylphosphonic acid (H~2~SPP) in order to functionalise the filler particles with strongly acidic sulphonic groups. The functionalised samples (Nafion/
