The purpose of work is investigation features of transition process under the solid and gas phase formation. Research reception is studying of electrochemical characteristics, mathematical modeling. Electroconductivity of the thin layers liquid at a surface air - electrolytes is investigated. Measurements pH value has been confirmed abnormal high electroconductivity of the superficial layer. Influence of the potential deviation from potential of the zero charge and also of current density on the detachable sizes oxygen and hydrogen bubbles size is investigated. It is shown, that at the deviation of the zero charge potential, reduction of the sizes bubbles takes place. Processes of carry of protons are investigated at solid-phase reactions in nickel oxide an electrode. It is proved, that at the category protons move in a crystal lattice on the mixed diffusion-migratory mechanism. Theestimation of values of parameter of structural activity is given. Stabilizing action of zinc and aluminium during the cyclic charge-discharge on property of the active material has been show. The further development of the research object is connected to optimization of electrochemical processes and electrodes of chemical power sources. The field of application is technical electrochemistry. Product Description popup.authors popup.nrat_date 2020-04-02 Close
