Abstract

The properties of TiO2/Nafion composite membranes were described. The limits of their applicability in proton exchange membrane fuel cells over the ranges of temperature and relative humidity were studied. The highest proton conductivity was obtained for the 5 mass % TiO2/Nafion membrane. The conductivity of the unmodified Nafion membrane was still higher than the conductivity of membranes with 10 and 20 mass % of TiO2 below 110°C.
