The emphasis of this project is to develop new, conductive ceramic materials and to produce structures from these materials for use as the components in the molten carbonate fuel cell (MCFC). The components under study include the cathode, anode, and interconnect, each of which is at a different stage of development. The cathode work focuses on assessing the viability of LiFeO{sub 2} as a replacement for the state-of-the-art NiO; this assessment relies on cell testing, with the performance data serving as the bases for component improvement. The anode studies seek to develop the required conductivity in a stable compound that exhibits little sensitivity to the range of anode oxygen partial pressures; this can be achieved through doping. The interconnect work emphasizes determining the effect of fuel and oxidant on conductivity, material properties, and structural integrity. 4 refs., 4 figs.
