Perfluorosulfonate ionomer dispersions in dimethylformamide solvent have been used to produce solution-cast membranes. Further, modified composite membranes have been prepared with the addition of low amount of silicate. In order to investigate the durability of such membranes vs commercial ones at low humidification conditions, longterm fuel cell experiments have been carried out. Results show that the addition of a low quantity of silicate in the polymeric membrane allows PEFC to operate at low humidification conditions, giving higher performances than those of unmodified Nafion™ 112 membrane and lowering system degradation.
