AI Article Synopsis
- Researchers studied a new carbon-supported copper complex (Cu-tri/C) as a cathode in alkaline H(2)/O(2) fuel cells, finding its performance comparable to traditional platinum (Pt/C) cathodes.
- Unoptimized Cu-tri/C showed higher mass activity at relevant potentials compared to other cathodes like Pt/C and silver (Ag/C).
- The study identified several degradation patterns over time, indicating that better catalyst and electrode preparation could further improve performance and durability.
Article Abstract
The performance of a novel carbon-supported copper complex of 3,5-diamino-1,2,4-triazole (Cu-tri/C) is investigated as a cathode material using an alkaline microfluidic H(2)/O(2) fuel cell. The absolute Cu-tri/C cathode performance is comparable to that of a Pt/C cathode. Furthermore, at a commercially relevant potential, the measured mass activity of an unoptimized Cu-tri/C-based cathode was significantly greater than that of similar Pt/C- and Ag/C-based cathodes. Accelerated cathode durability studies suggested multiple degradation regimes at various time scales. Further enhancements in performance and durability may be realized by optimizing catalyst and electrode preparation procedures.
