Development work on alternative cathode materials for the molten carbonate fuel cell is reported. The work has centered on improving and/or stabilizing the conductivity of LiFeO2 and Li2MnO3. The results of a variety of tests on doped samples (Mg, Mn, Cu dopants) are reported. Doping, although not yet optimized, has yielded stable materials with resistivities within a factor of ~2-5 of the original target value. Work is continuing to better understand and optimize these materials and to examine other dopants.
