The transition from hydrocarbon energy to hydrogen energy required the search for cost-effective technologies for the hydrogen production. In this paper, we propose a method for solving inverse problems arising when calculating the rate constants of near-electrode stepwise reactions in heterogeneous processes in systems "solid body—liquid electrolyte" with the substance disengagement in the gas phase. This numerical algorithm makes it possible to find the constant rates in the near-electrode processes in accordance with the specified experimental data on the yield, as well as to calculate the concentrations of substances participating in the near-electrode processes at specific points in time. The algorithm that implements the inverse problem is based on numerical optimization methods, while the solution of the kinetic equations system describing stepwise near-electrode reactions in a liquid electrode is solved by the Runge–Kutta method. The verification of this methods was carried out by comparing the results of full-scale study with the calculated data obtained by the mathematical model describing the hydrogen yield in a solution of potassium hydroxide. The results of numerical studies are in good agreement with the experimental data. [ABSTRACT FROM AUTHOR] |
