Given the relevance of renewable energy sources (solar, wind, etc.), the research focuses on studying electrochemical and mass transfer processes occurring in chemical current sources and finding solutions that can improve their energy performance. This work is aimed at a deeper understanding of the processes occurring in electrochemical generators and at determining the role of various structural materials, such as ion-exchange membranes, which are key elements in shaping the characteristics of generators. Since it is ion-exchange membranes that determine the efficiency and stability of the generators, it is important to explore the possibilities of their modification to increase energy efficiency, improve the thermal regime and increase the operating voltage of the generators. Another important aspect is the development of methods for automating the control of such systems and creating approaches to stabilize their operation under different loads and temperature changes. This will allow not only to improve energy performance, but also to increase the reliability of systems used in autonomous energy supply sources, in particular for magnetic levitation vehicles, urban transport, sparsely populated areas or facilities with limited access to central power grids. Thus, the aim of the work is to comprehensively improve energy supply systems based on electrochemical generators by: - Optimization of mass transfer processes and electrochemical activity to reduce energy losses. - Increasing the stability and durability of ion-exchange membranes and developing methods for their modification. - Study of thermodynamic and kinetic characteristics of reactions in systems using water-soluble active substances.
