Advanced fuel cell research and development activities at Argonne National Laboratory (ANL) during the period July-September 1979 are described. These efforts have been directed toward understanding and improving components of the molten carbonate fuel cells operated at temperatures near 925 K. The primary focus has been on the development of electrolyte structures that have good electrolyte retention and mechanical properties as well as long-term stability. A major effort this period has been on the synthesis of LiAlO/sub 2/ particles for the preparation of high-porosity (60%) sintered structures. The major problem has been avoidance of ionic species (unreacted Li/sub 2/CO/sub 3/ or LiOH) during sintering, which produce structures with excessive particle growth and low porosity. Initial cell tests with sintered electrolyte structures indicate that these structures can survive thermal cycles and that adequate wet seals can be obtained.
