NOVELTY - The electrical energy store comprises a storage cell. The storage cell comprises an air electrode, which is connected to air channels in an air supply device, and a storage electrode. The storage electrode adjoins a storage structure. Electrical contacts rest on the storage electrode, and are present in the form of an array of separate contact pins (12). The storage structure has a recess through which the contact pins extends. A contact network is arranged between the contact pins and the storage electrode. The contact pins have a diameter of 2-4 mm.    USE - Used as an electrical energy store.    ADVANTAGE - The cost-effective electrical energy store has high energy and power densities.    DETAILED DESCRIPTION - The electrical energy store comprises a storage cell. The storage cell comprises an air electrode, which is connected to air channels in an air supply device, and a storage electrode. The storage electrode adjoins a storage structure. Electrical contacts rest on the storage electrode, and are present in the form of an array of separate contact pins (12). The storage structure has a recess through which the contact pins extends. A contact network is arranged between the contact pins and the storage electrode. The contact pins have a diameter of 2-4 mm and a length of 17-21 mm as a distance between the contact pins. The store further comprises an interconnector plate, and a memory (32) disposed on an air side of the interconnector plate. A current path extends runs through component parts including a volume of material of a first interconnector plate, contact webs between the air channels of the first interconnector plate, the store electrode, a solid electrolyte, contact pins of a second interconnector plate and a volume of material of a second interconnector plate. The contact pins have rounded heads.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic exploded view of a stack of an electrical energy store.
