Abstract
An electric energy store includes a positive electrode, a negative electrode and an oxygen ion conducting electrolyte separating the positive electrode and the negative electrode from each other. The negative electrode includes a first reservoir having a gas-permeable oxidizable material and, contained therein, a gaseous, oxygen-exchanging redox pair. The positive electrode comprises a second reservoir having a gas-permeable oxidizable material and oxygen transport is effected by means of an oxygen-containing gaseous compound, wherein the positive electrode is closed with respect to the atmosphere.
