## 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

The physiochemical properties of Nafion 115 and a composite Nafion 115/zirconium phosphate (∼25 wt.%) membranes are compared. The composite membrane takes up more water than Nafion at the same water activity. However, the proton conductivity of the composite membrane is slightly less than that for N

## Abstract Gels of exfoliated α‐zirconium phosphate (ZrP~exf~) in dimethylformamide (DMF) were used to prepare Nafion/ZrP~exf~ composite membranes with filler loadings up to 7 wt.‐% by casting mixtures of Nafion 1100 solutions in DMF and suitable amounts of 2 wt.‐% ZrP gels in DMF. TEM pictures sh
