Abstract:
1. A molten carbonate fuel cell having an anode chamber, cathode chambers, and electrolyte area, supply lines for fuel gas and an output line for the resultant carbon dioxide and water on the anode chamber and supply lines for oxygen and carbon dioxide on the cathode chambers and output line for air oxygen and for substances containing carbon dioxide, characterized by the following features: a) the fuel cell is subdivided into an outer cathode chamber and a central cathode chamber, b) two separate electrolyte areas are arranged between the anode chamber and the central cathode chamber, as well as between the central and the outer cathode chambers, with c) an electrolyte channel passing through the central cathode chamber and/or the wall of the central cathode chamber, and d) the supply lines and output lines for oxygen being arranged on the central cathode chamber, and the supply lines and output lines for carbon dioxide being arranged on the outer cathode chamber, e) with the anode chamber and the central cathode chamber holding a metal sponge and/or a functional unit, and with the outer cathode chamber holding a metal and/or ceramic sponge or a module plate.
