- W3022588919 abstract "As an alternative for platinum to reduce the cost, nonprecious catalysts for the oxygen reduction reaction (ORR) were synthesized by deposition of an Fe/Co−Nx composite onto nanoporous carbon black with ethylenediamine (EDA) as a nitrogen precursor. Two different nanoporous carbon supports, Ketjen Black EC300J (KJ300) and EC600JD (KJ600), were used as catalyst supports for the nonprecious catalysts. Rotating ring disk electrode measurements were carried out to investigate the ORR activity and selectivity of these catalysts. The results obtained from the optimized FeCo/EDA-carbon catalyst, using KJ600 as the support, showed improved onset and half-wave potentials and superior selectivity than that of the KJ300. Similarly, the catalyst showed good performance in the hydrogen−oxygen PEM fuel cell. At a cell voltage of 0.6 V, the fuel cell managed to produce 0.37 A/cm2 with a maximum power density of 0.44 W/cm2. A fuel cell life test at a constant voltage of 0.40 V demonstrated promising stability up to 100 h..." @default.
