Abstract (Summary)

Proton Exchange Membrane Fuel Cell (PEMFC) technology is an exciting alternative energy prospect, especially in the field of transportation. PEMFCs are three times as efficient as internal combustion (IC) engines and emit only water as a byproduct. The latter point is especially important in a day and age when climate change is upon us. However, platinum required to catalyze the sluggish oxygen reduction reaction (ORR) which takes place on the cathode of the PEMFC has rendered fuel cell automobiles economically unviable. Therefore, the pursuit of an inexpensive replacement for platinum has become an active research area. Herein, a facile synthetic process for modified carbon nanotubes for ORR catalysis is described. These nanotubes display catalytic activity via rotating disc electrode (RDE) analysis which, in some cases, equals that of a Pt/C standard.
