  • REVERSE ELECTRODIALYSIS DEVICE USING PRECIPITATION REACTION, AND DRUG INJECTION DEVICE USING SAME
    Publication number: 20230098453
    Abstract: A reverse electrodialysis device using a precipitation reaction, according to one embodiment of the present invention, comprises a first cell stack alternately forming solid salt chambers and precipitation chambers through cation-exchange membranes and anion-exchange membranes which are alternately provided, and a first water-soluble solid salt and a second water-soluble solid salt which are filled in the solid salt chambers, wherein the first water-soluble solid salt and the second water-soluble solid salt are alternately filled in the solid salt chambers, and can react with each other so as to generate a precipitate in neighboring precipitation chambers when water is supplied.
    Type: Application
