Previously obtained high-temperature surface chemistry data and modeling results for the titania/water interface were used to analyze possible performance of titania microparticles in a composite titania/Nafion proton exchange membrane. The composite membrane exhibited higher proton conductivity compared to pure Nafion at 20-140°C and this observation correlated with the experimentally measured water uptake. Thus, titania/Nafion composite membrane can be considered as a promising material to be used in high-temperature proton exchange membrane fuel cells. This is an abstract of a paper presented at the 227th ACS National Meeting (Anaheim, CA 3/28/2004-4/1/2004).
