## 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/
