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.
