This project is to develop a new polymer electrolyte membrane structure for low
temperature proton transfer using both hydrogen and methanol as the fuels. This
membranes include an UHMWPE matrix embedded with proton transfer organo-nano platelet
silicate. A series of nanocomposite membranes, including Nafion/clay, Nafion/TiO2NT,
Nafion/clay/CNT, Nafion/CNT(SZ)AT/Pt, Nafion/CNT(SZ)AT/Pt/Clay, Nafion/CNT(SZ)AT/Pt/TiO2NT,
have been developed and characterized. The nanocomposite membranes show significant
improvement over the commercial membranes when assembled to an MEA (Membrane Assembly)
using the same electrode. The MEA performance of the Nafion/Pt on CNT/TiO2NT is
the best among all the nanocomposite materials. In addition, the multi-walled
carbon nanotube supported electrodes were also prepared and tested. A six-stack
prototype fuel cell has been constructured and being tested.
