REDOX FLOW CELL COMPRISING HIGH MOLECULAR WEIGHT COMPOUNDS AS REDOX PAIR AND SEMIPERMEABLE MEMBRANE FOR STORAGE OF ELECTRICAL ENERGY

摘要

It was an object of the invention to provide, by use of new materials and membranes and with very little outlay, an inexpensive and long-lived redox flow cell which even in the event of a possible serious accident brings about little environmental pollution by its redox-active compounds. According to the invention, high molecular weight compounds such as redox-active polymers or oligomers are provided as redox-active components and a size-exclusion membrane (3) is provided as membrane for the separation of the high molecular weight redox-active components.
