    • The present invention relates to a method for releasing oxygen from an aqueous electrolyte solution of a rechargeable redox flow battery, wherein at least two electrodes (E) are in electrically conductive contact with the electrolyte solution, at least one of the electrodes (E) is connected as an anode and at least one of the said electrodes is connected as a cathode and oxygen (O2) is formed on the anode, wherein no hydrogen or not more than 1.5 mol of hydrogen (H2) per 1.0 mol of oxygen (O2) formed is/are formed on the cathode. The invention further relates to an electrochemical cell comprising at least two electrodes (E), of which at least one is connected as a cathode and at least one is connected as an anode, wherein the electrodes (E) are located in at least one half-cell of a rechargeable redox flow battery and/or there is a fluid connection between the electrochemical cell and at least one half-cell of a rechargeable redox flow battery. The invention further relates to the use of electric current for releasing oxygen from an electrolyte solution of a rechargeable redox flow battery.
    • 本发明涉及一种从可再充电氧化还原液流电池的电解质水溶液中释放氧气的方法,其中至少两个电极(E)与电解质溶液导电接触,至少一个电极(E)是 作为阳极连接,并且所述电极中的至少一个连接为阴极,并且在所述阳极上形成氧气(O 2),其中每1.0摩尔氧气(O 2)不含氢或不多于1.5摩尔氢气(H 2) 形成在阴极上。 本发明还涉及一种电化学电池,其包括至少两个电极(E),其中至少一个连接为阴极并且至少一个连接为阳极,其中电极(E)位于至少一个电极 并且/或者在电化学电池和可再充电氧化还原液流电池的至少一个半电池之间存在流体连接。 本发明还涉及使用电流从可再充电氧化还原液流电池的电解质溶液中释放氧。
