Abstract
A battery has a cathode and an anode, between which a solid electrolyte is disposed. The battery has a process gas feed on the cathode side. The battery is characterized in that an electrically conductive supporting body is disposed on the cathode surface. At least one chamber connected to the anode has a porous, oxidizable material and a redox pair that is gaseous at an operating temperature of the battery.
Claims18
A battery comprising:
- a first electrode supplied with a process gas;
- a second electrode;
- a solid state electrolyte positioned between the first and second electrodes;
- a reservoir which is open to the second electrode and closed to an environment;
- a gas-permeable, oxidizable material arranged within the reservoir;
- a redox pair present within the reservoir and on a surface of the second electrode, the redox pair being gaseous at an operating temperature of the battery, wherein the redox pair is based on hydrogen and water and a reaction between the water and the oxidizable material takes place;
- and
- an electrically conductive support body that encloses the reservoir and is arranged on the second electrode.
