This dataset contains the data presented in the figures of pulbished paper "Electrospun Polyacrylonitrile-Derived Co or Fe Containing Nanofibre Catalysts for Oxygen Reduction Reaction at the Alkaline Membrane Fuel Cell Cathode" ChemCatChem 12, 4568 –4581 (https://doi.org/10.1002/cctc.202000658)
The electrochemical characterisation data, which was measured in University of Tartu Institute of Chemistry, is for Figures 5, 6, 7, S5, S6, S7, S8, S9 and the nomenclature of the catalysts is the same as in the mentioned article.

Data was collected using Autolab potentiostat/galvanostat PGSTAT30 (Metrohm Autolab, The Netherlands) controlled with NOVA version 2.1.4 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 the geometric area of 6.25 cm2 and active area of 5 cm2.

For Figures 5, 6, 7, S5, S6, S7, S8, S9 electrochemical data the measured currents have been converted from current (A) to current densities (mA/cm2).
For Figures 5c, 6, S5, S6, S7, S8, S9 the background currents, measured in Ar-saturated solution, have been subtracted, in addition to conversion to current densities (mA/cm2).
