DEVICE AND METHOD FOR PERFORMING A REVERSED ELECTRODIALYSIS PROCESS

摘要

The invention relates to a device for performing a reversed electrodialysis reaction. The device comprises a number of anode compartments provided with an anode and a number from the anode compartments separated cathode compartments provided with a cathode . The anode compartments and cathode compartments are separated by a number of cation exchange membranes and anion exchange membranes, placed alternatingly between the cathode and anode. Between these cation exchange membranes and anion exchange membranes compartments, the electrolyte compartments, are formed. In the electrolyte compartments low osmotic electrolyte solutions, having low electrolyte concentrations, and high osmotic electrolyte solutions, having electrolyte concentrations higher than the low osmotic electrolyte solutions are placed alternatingly. The device is characterized by the presence of a fluidum comprising Fe(III) and Fe(II) in the cathode compartments and anode compartments respectively. According to a further aspect the invention relates to a method for generating electric energy, wherein use is made of the device according to the invention.
