Dr. James C. Moller "Dr. Moller's research involves the exploration of molecular transport and morphology in hydrated polymer membranes for fuel cells. His work is accomplished with molecular dynamics simulations. He has developed scripts to model the proton hopping among hydronium and water molecules for the purpose of accurately predicting membrane system conductivity and has analyzed nanoscale kinetics and ordering."


Description of Research
This research responds to a critical need for a fundamental understanding of atomic-level transport in polymer electrolyte fuel cell membranes. The success of this project will be measured by the guidance it provides to the selection of the next generation of fuel cell membrane materials.

One objective is to explore the factors that enhance proton diffusion across the membrane. These include membrane pore size, polymer degree of sulfonation, and energy barriers to proton hopping. A second objective is to explore the factors that strengthen the hydrated membrane. These include pressure, temperature, humidity, and mechanical strain.

It is expected that these efforts will lead to the discovery of ways to enhance fuel cell membrane conductivity and strength. Progress in these areas is essential for making fuel cells viable alternatives to traditional power sources. This work has been performed in collaboration with researchers at the Air Force Materials Laboratory.
