Since the surface properties of solid oxides, such as zeta potential, surface charge density, and stoichiometry of surface complexes reflect the interfacial behavior of solid oxide particles, detailed surface studies can help to predict the performance of a particular oxide material in the composite membranes for high-temperature proton exchange membrane (PEM) fuel cells. Some electrochemical parameters of the electrical double layer (EDL) on the solid oxide surface were discussed in relation to ionic conductivity and water retention of solid oxide/Nafion composite membranes. The zeta potential values measured at the TiO2/water interface at elevated temperatures helped to explain some advantages of these composite membranes in PEM fuel cell operation at low relative humidity. copyright The Electrochemical Society.
