Formation of the honeycomb-like electrodes of copper by the regime of reversing current (RC) in the second range has beeninvestigated. Morphological and structural characteristics of this electrode type obtained by various parameters of RC regimeswere examined by the techniques of scanning electron and optical microscopies, while the amount of hydrogen produced duringelectrodeposition process was quantified by determination of the average current efficiency for hydrogen evolution reaction. Tooptimize the process of formation of the honeycomb-like electrodes, the following parameters of square wave RC regimes wereanalyzed: the cathodic current density, the same anodic to cathodic time ratios but various durations of the cathodic and theanodic pulses, and the various values of the anodic to cathodic time ratios. The minimal amount of hydrogen spent for formationof the honeycomb-like electrodes with maximal number of holes formed from detached hydrogen bubbles is obtained with theanodic t...o cathodic time ratio of 0.50 and duration of the cathodic and anodic pulses of 2 and 1 s, respectively. To explainformation of the honeycomb-like electrodes of optimal morphological and structural characteristics, the upgraded mathematicalmodel defining the RC regime in the second range was proposed and discussed.
