    摘要： A hybrid flow redox battery system includes an electrochemical cell with an ion-exchange membrane, an anode, and a cathode, an anolyte tank, a catholyte tank, one or more tank separators, a plurality of electrolyte pathways, one or more turbines, and one or more power generation circuits. The anolyte tank includes a lower anolyte opening positioned below an upper anolyte opening. The catholyte tank includes a lower catholyte opening positioned below an upper catholyte opening. The electrolyte pathways extend between the upper and lower anolyte openings and the anode and the upper and lower catholyte openings and the cathode. The turbines are fluidly coupled to the electrolyte pathways. The tank separators are positioned within one or both of the anolyte tank and the catholyte tank and are translatable in a downward direction to induce electrolyte flow from the lower anolyte and catholyte openings, through the turbines to hydroelectrically generate power.

    摘要： According to one embodiment of the present disclosure, a redox flow battery is provided comprising an ionically conductive separator, a working side flowing electrolyte, a working electrode in ionic contact with the working side of the ionically conductive separator and the working side flowing electrolyte, a counter electrode, and an auxiliary electrode peripherally circumscribed by the working electrode in a common layer of the flow battery. The auxiliary electrode is in ionic contact with the working electrode, an electrically insulating peripheral gap separates the auxiliary electrode from the working electrode. A working electrode terminal is conductively coupled to the working electrode, an auxiliary electrode terminal is conductively coupled to the auxiliary electrode, and a counter electrode terminal is conductively coupled to the counter electrode. An auxiliary power source is configured to establish an auxiliary circuit voltage differential between the counter electrode terminal and the auxiliary electrode terminal, control an auxiliary electrode voltage such that the auxiliary electrode voltage is within an electrochemical window of the working side flowing electrolyte, and establish a voltage differential between the working electrode terminal and the auxiliary electrode terminal. A method of operation of the redox flow battery is further provided.

    摘要： A method for co-processing H2S and CO2 in an electrolyzer includes feeding a first gas stream having H2S to an anode and feeding a second gas stream having CO2 to a cathode. The H2S is split into hydrogen and elemental sulfur. The hydrogen is transferred from the anode to the cathode, and the CO2 is hydrogenated with the transferred hydrogen. A method for producing electricity in a fuel cell includes feeding a first gas stream having H2S and CO to an anode, and feeding a second gas stream having oxygen to a cathode. The H2S and CO forms hydrogen and carbonyl sulfide. The hydrogen is transferred from the anode to the cathode. The transferred hydrogen is oxidized with the oxygen of the second gas stream, and electricity formed from the oxidation is collected.
