This technology provides for a new class of carbon-based, low-cost, metal-free ORR (oxygen reduction reaction) catalysts that have been demonstrated to show superior ORR performance to commercial platinum catalysts in acidic electrolytes. These rationally designed, metal-free, nitrogen-doped carbon nanotubes and their graphene composites have also exhibited significantly better long-term operational stabilities and comparable gravimetric power densities with respect to the best NPMC (non-precious metal catalysts) in acidic PEM cells. This work represents a major breakthrough in removing the bottlenecks to translate low-cost, metal-free, carbon-based ORR catalysts to commercial reality, and opens avenues for clean energy generation from affordable and durable fuel cells.Provisional application 62/120,675 has been filed and a paper published describing this work in Science Advances, 27 Feb. 2015.
