This dataset contains the data presented in the figures of pulbished paper "Oxygen reduction reaction on Pd nanoparticles supported on novel mesoporous carbon materials" Electrochimica Acta 394 139132 (https://doi.org/10.1016/j.electacta.2021.139132)
The data is for Figures 6-14. Nomenclature is as follows: PdSupport. If Pd loading was varied in the figure PdSupport_loading. Data uses shortened nomenclature example: ECS-003604 is shortened to 3604. Figure 14 uses Pd loading of 40% for both catalysts. If no Pd is in the nomenclature measurement was carried out using only the support material. Figure 9a and 11a uses Pd3604_30 with row titles referring to varying electrode rotation speeds in rpm.

Data was collected using Autolab potentiostat/galvanostat PGSTAT30 (Metrohm Autolab, The Netherlands) controlled with General Purpose Electrochemical System (GPES version 4.9.007) software. The working electrode was glassy carbon electrode with diameter of 5 mm.  
Single cell AEMFC performance evaluation was conducted using Greenlight Fuel Cell Test Station (G40 Fuel cell system, Hydrogenics, Vancouver, Canada). Catalyst was pippeted on gas diffusion layers with geometric area of 5 cm2.

For all supplied electrochemical data the measured currents have been converted from current (A) to current densities (mA/cm2).
For Figure 9-13, the background currents, measured in Ar-saturated solution, have been subtracted, in addition to conversion to current densities.
