摘要： A system includes one or more redox flow batteries and includes a stack of several electrochemical cells. The electrochemical cells include a cathode compartment and an anode compartment. The cathode compartment is in fluidic communication, via a feed circuit, with one or more tanks of electrolyte called catholyte. The anode compartment is in fluidic communication, via a feed circuit, with one or more tanks of electrolyte called anolyte. The feed circuit of the catholyte, respectively the anolyte, includes a pump for circulating the catholyte, respectively the anolyte, from the tank to the cathode, respectively the anode compartments. The system includes a catholyte drainage pump and an anolyte drainage pump, the catholyte, respectively. The anolyte drainage pump is controlled by a catholyte, respectively anolyte presence detector, in at least a part of the feed circuit of catholyte, respectively anolyte.

摘要： Devices and methods for managing the state of health of an electrolyte in redox flow batteries (RFB) efficiently are described. A diffusion cell is added to the RFB which controls one or more properties of the electrolytes using the diffusion of protons through a proton exchange membrane. The diffusion cell can resemble an electrochemical cell in that there are two fluid chambers divided by a proton conducting membrane. Anolyte flows through one side of the device where it contacts the proton conducting membrane, and catholyte flows through the second side of the device where it contacts the other face of the proton conducting membrane. The concentration gradient of protons from high concentration in the catholyte to low concentration in the anolyte is the driving force for proton diffusion, rather than electromotive force, which greatly simplifies the design and operation.
