“…The costs are generated by electrodes made of noble metals (platinum, palladium, iridium, ruthenium) that exhibit a suitable hydrogen evolution overpotential. Transition effect of under‐ and over‐potentially deposited hydrogen on Pd [5] and Rh [6] examined. In order to reduce electrolysis costs, alternatives to noble metal electrocatalysts are being sought [7] …”

A mathematical model of simultaneous cobalt deposition and hydrogen evolution was developed and applied to the electroreduction process of 5 mM Co2+ ions investigated by cyclic voltammetry (CV) technique at different hydrogen ion concentrations (pH=2, 3, 4). The kinetic parameters of such a complex process were determined, and the validity of the model and its sensitivity to changes in individual parameters were verified. The relative value of the approximate standard deviation (ASD%) was used to determine the degree of fit of the model to the experimental data. The catalytic effect of cobalt on the hydrogen evolution process was comprehensively confirmed.
