Abstract:
A method of operating a molten carbonate fuel cell, which fuel cell comprises a porous anode, a carbonate-comprising matrix and a porous cathode, wherein the anode is supplied with a hydrogenous gas and the cathode is supplied with a mixture of an oxygenous gas and a primary carbon dioxide, the fuel cell is operated at a temperature in a range of approximately 600.degree. C. and above, with the carbonate of the carbonate-comprising matrix being in a fluid state, oxygen and carbon dioxide are reacted at the cathode, yielding carbonate ions which move from the cathode to the anode generating an electric voltage between the anode and the cathode, and water that has been formed is led away from the fuel cell together with carbon dioxide, characterized in that the carbonate-comprising matrix is provided with a channel and via said channel primary carbon dioxide-comprising gas is introduced into the carbonate-comprising matrix at a distance from the cathode.
