Abstract
An original method for producing Ni–Co electrodes is proposed in this paper. The electrochemical behavior of these electrodes was studied in an alkaline electrolysis cell. It was found that the obtained electrodes exhibit catalytic activity with respect to the oxygen evolution reaction, reducing the overvoltage of this process, for example, at high current densities and a temperature of 85°C by 390 mV compared to the Ni electrode. The advantage of the obtained electrodes is the absence of any coating on their surface that can peel off during operation, leading to irreversible degradation of the electrode. The studied Ni–Co electrodes were tested in 6 M KOH at a temperature of 85°C and a current density of 300 mA/cm2, i. e. under conditions as close as possible to operating conditions for alkaline electrolyzers for 500 hours. It was shown that after the tests, the electrode surface remained without visible signs of degradation such as cracking, delamination and other mechanical damage. At the same time, a small but irreversible increase in voltage is noted on the volt-ampere characteristics, which may indicate a decrease in the catalytic properties of the electrode surface.
