1. A method for charging or discharging an energy store having a first electrode, which, by donating electrons to a component of a process fluid, can produce anions from said component or, by accepting electrons from anions, can consume said anions by neutralization of the charge thereof and release to the process fluid, a second electrode, which, by releasing electrons, can produce anions or, by accepting electrons, can consume anions, an electrolyte, which is arranged between the first electrode and the second electrode and conducts anions, and a first redox pair, which comprises a first oxidation reactant and a first oxidation product, in which the first oxidation product is reduced in order to charge the energy store, and the first oxidation reactant is oxidized in order to discharge the energy store, wherein
use is made of a fluidic redox pair which comprises a fluidic oxidation reactant and a fluidic oxidation product and is in contact with the first redox pair and the second electrode, during the discharge of the energy store, the fluidic oxidation product is reduced to the fluidic oxidation reactant at the first oxidation reactant, producing the first oxidation product in the process, and the fluidic oxidation reactant is oxidized to the fluidic oxidation product at the second electrode by means of the anions, donating electrons to the second electrode in the process, and during the charging of the energy store, the fluidic oxidation reactant is oxidized to the fluidic oxidation product at the first oxidation product, producing the first oxidation reactant in the process, and the fluidic oxidation product is reduced to the fluidic oxidation reactant at the second electrode, wherein anions are generated at the second electrode by accepting electrons from the second electrode, wherein the fluidic redox pair is gaseous during the oxidation and reduction, and wherein a pressure above the ambient pressure of the medium surrounding the energy store is maintained in the fluidic redox pair. |
