Abstract
The flow battery utilizing caustic waste includes at least one battery cell (100), which is formed from an ion-exchange membrane (106) disposed between porous anode and cathode electrode layers (108, 104). A cathode bipolar plate (102) is positioned adjacent the porous cathode electrode layer (104) and, similarly, an anode bipolar plate (110) is positioned adjacent the porous anode electrode layer (108). The anode bipolar plate (110) is adapted for receiving spent caustic waste and transporting the spent caustic waste to the anode electrode layer (108), and the cathode bipolar plate (102) is adapted for receiving an oxidant and transporting the oxidant to the porous cathode electrode layer (104) for generation of electricity while converting the spent caustic waste (303) into fresh caustic (306).
