N2  - YMnO3 perovskites synthesized using the sol-gel method were studied regarding their electrocatalytic properties for the O2 and H2 evolution reactions (OER and HER) in a strong alkaline medium. The highest activity was observed during HER experiments, especially for the electrodes manufactured using suspensions containing Nafion, Carbon Black and either Co2+ doped YMnO3 or Sn2+ doped YMnO3. For these samples, the HER overpotential value at i = ?10 mA/cm2 was 0.83 V. The main conclusions are the following: (a) the inclusion of Carbon Black into the electrode manufacturing process improved the HER catalytic activity of all perovskite-modified electrodes and (b) the HER activity of the samples modified with the catalysts, Nafion and Carbon Black was similar despite the different temperatures applied during perovskite synthesis.
