  • Electrical energy store
    Patent number: 9583804
    Abstract: An energy store is provided, having at least one stack, each stack having at least one storage cell, which in turn has an air electrode and a storage electrode. The storage electrode is adjacent to channels, which contain a storage medium and water vapor. The channels have a larger cross-sectional area than the cross-section of the storage medium, which condition causes unhindered spreading of a reaction gas in the area between the storage electrode and the storage medium.
