Argonne’s Porous Nano-Network Catalyst, which won a 2016 R&D 100 award, revolutionizes the non-precious metal catalyst design and synthesis simultaneously at the active site and electrode architecture levels. It offers the highest possible active site density and significantly improves charge and mass transfers using low-cost chemicals and earthly abundant materials.
The catalysts are demonstrated to be highly effective toward oxygen reduction reaction, a key electrochemical reaction at the fuel cell cathode, in both acidic and basic environments, making it applicable to both proton exchange membrane and alkaline membrane fuel cells. The new catalyst outperforms the best benchmarked NPMC by 76 percent and approaches Pt/C in acidic media, and outperforms Pt/C in alkaline media in both activity and durability. It also led to 20 to 25 times cost saving in the catalyst material, rendering it an attractive and viable replacement for the expensive precious metal catalysts in the practical fuel cell applications.
Each year for more than 50 years, R&D Magazine has honored the 100 best innovations in research and development. We are currently accepting applications for the 2017 R&D 100 Awards. Innovators with an exceptional product developed between January 1, 2016 and March 31, 2017 should apply. Submissions close April 14, 2017
