ELECTROCHEMICAL SET TO ACCUMULATE AND/OR FEED ENERGY Russian patent published in 1998 - IPC

FIELD: electrical engineering. SUBSTANCE: electrochemical set to accumulate and/or generate energy includes assemblage of cells. Each cell has positive and negative electrodes, membrane dividing cell into catolyte and anolyte chambers including catolyte and anolyte solutions that recycle through separate pumps and storage vessels back to chambers. Intermediate electrodes positioned between adjacent cells in assemblage have both positive and negative sides. Set uses pair bromine-sulfur. It is fitted with aids for compensation of changes of pH and/or changes of concentrations of hydroxyl-ions by positive and/or negative sides of assemblage of cells. There is envisaged aids acting on existing limiting migration through membrane or other losses of bromine, sulfur and/or water and on limitation of acidification effect at the expense of bromine with maintenance of high energy accumulation efficiency, obtainment of high power with stable operation in the course of long-term periods and keeping of energy output and high level of voltage during practically whole discharge cycle. EFFECT: enhanced operational efficiency of set. 12 cl, 12 dwg
