The Purpose of work is research the particularities of the processes in electrochemical system with big surface between electrolyte and solid or gas phase. Research reception is the analysis of conductivity, electrochemical and X-ray diffraction analysis, derivatography. It is investigated influence of the temperature and ion composition on the conductivity and near interphase boundary "air-electrolyte". It is shown that efficient surface conduction increases with reduction of the films thickness from 1 mm to ~0,5 мкм more than on 2 orders. It is ascertained that the efficient conduction has been increased synchronously with increasing of the temperature and concentration of the inorganic ions. It is studied the influence of the specific surface value of the solid reagent on electrochemical processes. The synthesized various modifications Ni(OH)2, is studied their structure and electrochemical features. It Is designed mathematical model to nonlinear protron diffusion in solid phase and model of the electrochemical recrystallization. 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 theoretical and technical electrochemistry.
