Battery and method for operating a battery

摘要

The invention relates to a battery comprising a cathode (6) and an anode (10), between which a solid electrolyte (6) is disposed. The battery comprises a process gas feed on the cathode side. The battery is characterized in that an electrically conductive supporting body (12) is disposed on the cathode surface (13), comprising in turn at least one chamber (14) connected to the anode, comprising a porous, oxidizable material (16) and a redox pair that is gaseous at an operating temperature of the battery.
