This dataset contains the data presented in the figures of published paper "Binary transition metal and ZIF-8 functionalised polymer-derived ceramic catalysts for high temperature PEM fuel cell cathode" Electrochimica Acta 514 145620 (https://doi.org/10.1016/j.electacta.2024.145620).
The electrochemical characterisation data, which was measured in DLR Institute of Engineering Thermodynamics, Oldenburg, Germany, is for Figures 7-11, S4-S13 and the nomenclature of the catalysts is the same as in the mentioned article.

Data was collected using the following instruments:
Autolab potentiostat/galvanostat PGSTAT204 equipped with RRDE Rotator and Motor Controller (Metrohm) controlled with NOVA version 2.1 software (Figures 7-9, S4-S12);
potentiostat Modulab2100A (Ametek) equipped with an external booster (12 V/20 A) (Figures 10-11, S13);
GDE single cell FlexCell® PTFE (Gaskatel) setup (Figures 10, S13);
HT-PEM single cell test station from  Inhouse Engineering equipped with a quickCONNECTfixture (qCF 5/100 HT, balticFuelCells) (Figure 11).

For Figures 7-11, S4-S13 electrochemical data, the currents have been converted from current (A) to current densities (mA/cm2).
For Figures 7-9, S4-S6, S8-S12 the background currents, measured in Ar-saturated solution, have been subtracted, in addition to conversion to current densities.
