The electrochemical activity of nickel mesh cathodes activated by electrocatalysts of chemically deposited coatings Ni-S-Fe is investigated. The maximum reduction of overvoltage at current density 6 kA/m2 and temperature 70°C is 0.34 V. Comparison of the electrochemical activity of such cathodes with similar cathodes described in the scientific literature revealed that at the same temperature and same overvoltage the current density is twice higher than for the known electrodes.
