Dataset of "Performance and stability of PtCo alloy catalysts in high-temperature polymer electrolyte membrane fuel cells"

This study investigates the performance of two novel PtCo alloy catalysts for high-temperature polymer electrolyte membrane fuel cells (HT-PEMFCs). The catalysts were supported either on carbon black or reduced graphene oxide and were prepared by a patented method devised by the Slovenian part of the author team. The aim of this study was to was to investigate the activity of these catalysts and shed light on the Co lifecycle in an HT-PEM single cell. The dataset includes the results of electrochemical measurements and ex-situ instrumental analyses, both of pristine materials and post mortem samples.
