A method of operating a molten carbonate fuel cell having an anode and a cathode and in between a matrix comprising molten carbonate. Carbon dioxide is introduced into the matrix at a distance from the cathode. This greatly reduces the cathode's deterioration and in the system design increases the control potential of the fuel cell. A fuel cell...
