Investigation of the activity and stability of Pd-based catalysts towards the oxygen reduction (ORR) and evolution reactions (OER) in iron-air batteries

Pd-based catalysts supported on commercial carbon supports (Ketjenblack and Vulcan) have been studied for both the ORR and the OER. Pd proved to be a suitable bi-functional catalyst for the ORR and the OER, with Vulcan as the carbon support providing the highest stability during accelerated degradation tests.
