| 摘要 |
An electrochemical process for energy storage and/or power delivery in a single cell or in an array of repeating cell structures, each cell with a +ve chamber (22C) containing an inert +ve electrode (12) and a -ve chamber (24C) containing an inert -ve electrode (14), the chambers being separated one from another by an ion exchange membrane (16), the electrolyte circulating in the -ve chamber (24C) of each cell during power delivery containing a sulfide, circulating in the +ve chamber (22C) during power delivery containing a liquid oxidising agent, which process affords compensation for pH changes and/or changes in the concentration of hydroxyl ions in the +ve chamber (24C) by the generation of OW ions and hydrogen gas by the decomposition of water. Also disclosed is an apparatus wherein the formation of hydroxyl ions by the decomposition of water is carried out in a electrochemical cell (36, 45) |
