INFLUENCE OF THE TYPE OF ELECTRODE MATERIAL ON THE LOAD PARAMETERS OF MEMBRANE-ELECTRODE UNIT OF REDOX FLOW BATTERY
We study the influence of the type of electrode material on load parameters of a membrane-electrode unit of redox flow batteries for determination the optimal configuration of an experimental battery and reducing economic costs of its manufacturing. It has been established that for the developed experimental sample of vanadium redox flow battery for an electrolyte of 1M V in 4 M H2SO4, it is sufficient to use two layers of carbon paper as electrodes instead of three that are considered optimal due to a decrease in internal resistance and associated losses. The article provides the structure of the experimental sample of the membrane-electrode unit and the algorithm for testing vanadium redox flow batteries; according to the results of the experiments, the characteristics of membrane-electrode blocks containing three, two, and one layer of Sigracet 39 AA carbon paper as electrodes without preliminary processing were evaluated.
