Electrodes modified using aggregated cobalt-porphyrin/polymer ligand systems were prepared and electro-catalytic activity for oxygen (O<sub>2</sub>) reduction was investigated physicochemically. The maximum value of water yield due to O<sub>2</sub> four-electron reduction was 56%. The apparent number of electrons involved in O<sub>2</sub> reduction was 2.7 to 31. Two reactions due to O<sub>2</sub> two- and four-electron reduction occurred on modified electrodes. Modification (adsorption) stability of the electrocatalyst system was over a few hours under hydrodynamic conditions.
