Herein, we address hybrid materials composed of three representative N-doped carbon supports (BP-2000, Vulcan XC-72 and P-CNF) with valid surface areas and different series of single, double and triple perovskites: Ba<sub>0.5</sub>Sr<sub>0.5</sub>Co<sub>0.8</sub>Fe<sub>0.2</sub>O<sub>3-δ</sub>, (Pr<sub>0.5</sub>Ba<sub>0.5</sub>)CoO<sub>3-δ</sub>, and Nd<sub>1.5</sub>Ba<sub>1.5</sub>CoFeMnO<sub>9-δ</sub> (NBCFM), respectively. The combination of NBCFM and N-doped BP-2000 produces a half-wave potential of 0.74 V and a current density of 5.42 mA cm<sup>-2</sup> at 0.5 V versus reversible hydrogen electrode, comparable to those of the commercial Pt/C electrocatalyst (0.76 V, 5.21 mA cm<sup>-2</sup>).
