Nafion 112 membranes were soaked in 1 M H 2 SO 4 solutions containing variable amounts of Fe and Cr ions, either individually or mixed. An even distribution of the metal ions on the surface of the membranes was observed with electron probe microanalysis (EPMA) mapping. The proton conductivity of the

## Abstract A casting process for composite Nafionยฎ/STA membranes was achieved. The membrane casting was based on the evaporation of 5% Nafionยฎ solution in N,Nโฒโdimethylformamide (DMF) with and without silicotungstic acid (STA) as an additive. Optimized parameters for the casting process were deter
