The conventional cathode material for a molten carbonate fuel cell (MCFC) is NiO. However, these cathodes have limited longevity due to dissolution at cathode conditions and precipitation as metal at anode conditions. Alternative cathode materials are being sought through a process of identifying stable materials in the cathode environment, evaluating their properties, and modifying their conductivity through doping. The work has centered on LiFeO/sub 2/ and Li/sub 2/MnO/sub 3/ which are stable, have low solubility, and do not migrate under cell conditions. LiFeO/sub 2/ can be produced with resistivity in the range of 10 to 40 ohm-cm at 650/sup 0/C in realistic cathode gases.
