摘要： A method of operating a redox flow battery includes a step of observing a difference in relative volume between the anolyte fluid volume and the catholyte fluid volume. The ionic molality of anolyte fluid is increased if the relative volume of the anolyte fluid decreases. A redox flow battery having balanced anolyte and catholyte initial ionic molalities is also provided.

摘要： A fuel cell stack system is configured to uniformly supply a fuel or an electrolytic solution to each of fuel cell elements, and an electronic device using the fuel cell stack system are provided. An electrolytic solution channel allowing an electrolytic solution to flow therethrough is arranged between a fuel electrode and an oxygen electrode, and a fuel channel allowing a fuel to flow therethrough is arranged outside of the fuel electrode. The electrolytic solution channels and the fuel channels of all fuel cell elements are connected in series to one another. That is, the fuel or the electrolytic solution emitted from an outlet of the fuel channel or the electrolytic solution channel of one fuel cell element enters into an inlet of the fuel channel or the electrolytic solution channel of the next fuel cell element through a connection channel. In addition, either or both of the electrolytic solution channels and the fuel channels of some or all of the fuel cell elements may be connected in series to one another.

摘要： The present disclosure relates to an electrochemical cell comprising a fuel electrode for oxidizing a fuel, an oxidant electrode for reducing an oxidant, and an ionically conductive medium for conducting ions between the fuel and oxidant electrodes to support electrochemical reactions at the fuel and oxidant electrodes. The ionically conductive medium comprises at least one active additive for enhancing (controlling the rate, overpotential and/or the reaction sites for) at least one electrochemical reaction within the cell. The cell further comprises an additive medium in contact with the ionically conductive medium and containing the at least one active additive capable of corroding or dissolving in the ionically conductive medium. The additive medium and/or casing is configured to release the active additive to the ionically conductive medium as a concentration of the active additive in the ionically conductive medium is depleted during operation of the cell.

摘要： The fuel cell discussed herein includes embodiments a drive load, a load switch connecting either of a steady state load and a drive load to a fuel cell, and a load adjuster adjusting a value of the drive load. w A load switch switches the load of the fuel cell to the drive load in the drive period of the fuel cell, the load adjuster increases step by step the load of the drive load. The load switch switches, when the drive load reaches a predetermined value, the load of the fuel cell to the steady state load from the drive load.

摘要： Various methods of rebalancing electrolytes in a redox flow battery system include various systems using a catalyzed hydrogen rebalance cell configured to minimize the risk of dissolved catalyst negatively affecting flow battery performance. Some systems described herein reduce the chance of catalyst contamination of RFB electrolytes by employing a mediator solution to eliminate direct contact between the catalyzed membrane and the RFB electrolyte. Other methods use a rebalance cell chemistry that maintains the catalyzed electrode at a potential low enough to prevent the catalyst from dissolving.

摘要： Methods, systems and structures for monitoring, managing electrolyte concentrations in redox flow batteries are provided by introducing a first quantity of a liquid electrolyte into a first chamber of a test cell and introducing a second quantity of the liquid electrolyte into a second chamber of the test cell. The method further provides for measuring a voltage of the test cell, measuring an elapsed time from the test cell reaching a first voltage until the test cell reaches a second voltage; and determining a degree of imbalance of the liquid electrolyte based on the elapsed time.
