Nanostructured oxygen reduction catalyst designs to reduce the platinum dependency of polymer electrolyte fuel cells
Higgins, Drew Christopher (University of Waterloo, 2015-07-24)Polymer electrolyte fuel cells (PEFCs) are electrochemical devices that efficiently convert hydrogen and oxygen into electricity and water. Their clean point of operation emissions and fast refueling times have resulted ... -
Nitrogen-Doped Carbon Nanotubes and their Composites as Oxygen Reduction Reaction Electrocatalysts for Low Temperature Fuel Cells
Higgins, Drew Christopher (University of Waterloo, 2011-05-03)The extensive amount of platinum required in order to facilitate the oxygen reduction reaction (ORR) occuring at the cathode of low temperature fuel cells provides cost limitations to the sustainable commercialization of ...
