FUNCTIONAL LAYOUT FOR STUDYING THE STRUCTURE AND DEMONSTRATING THE OPERATION OF A FLOW REDOX BATTERY Russian patent published in 2022 - IPC H01M8/18 G09B23/34 

FIELD: electrochemistry.

SUBSTANCE: claimed invention relates to educational and research equipment in the field of alternative energy and electrochemistry and can be used as a material base for conducting full-scale tests of flow redox batteries in research centers (institutions), or an educational and methodological object during workshops and laboratory work in educational institutions as part of the study of electrochemistry, courses of general chemistry, physics, physical chemistry, distributed energy and related disciplines. The claimed device is a prototype of a real object that appeared not so long ago in the world of practical application: a flow redox battery. It has an industrial appearance, which corresponds to its purpose: to show the true structure of the FRBs, their appearance and to enable the researcher/trainee/student to perform various manipulations aimed at controlling the processes taking place, studying them and, most importantly, understanding them as they are. A functional layout for studying the structure and demonstrating the operation of a flow redox battery includes a flow redox battery (stack), which is attached to a mounting plate with electrolyte tanks. The mounting plate, in turn, consists of two electrolyte tanks, which are fixed between a Teflon plate, in which there is a system of channels for the flow of electrolyte from the tank to the stack and back to the tank, two fluorine-rubber gaskets that give tightness and chemical resistance, and two duralumin plates that give rigidity and tightness to the mounting plate described above. All the indicated components of the mounting plate have through holes for being strapped together. On the lower part of this plate, in the middle, between the tanks, a pumping module is attached, designed to circulate electrolytes from both tanks through the stack.

EFFECT: possibility of visually studying the specifics of such a type of chemical current sources (CCS) as flow redox batteries (FRB), which makes it possible to test FRBs of various power and energy intensity, overall dimensions; the device involves the use of electrolytes of various composition, has a hoseless connection of the main functional units and the possibility of autonomous operation in the form of a chemical current source.
