| Fuel Cell and Catalysis
Fuel
cells are promising candidates for alternative energy sources.
Challenges faced include power lost at the cathode during the oxygen
reduction reaction (ORR) and the high cost of Pt in the currently most
effective catalysts. Our focus in this project is on elucidating the
steps of the ORR reaction and investigating novel catalyst materials
using a combination of surface and bulk sensitive experimental
techniques using synchrotron radiation.
