Advanced fuel cell development. Progress Report, April-June 1980. [LiAlO/sub 2/]
Advanced fuel cell research and development activities at Argonne National Laboratory (ANL) during the period April-June 1980 are described. These efforts have been directed toward understanding and improving components of molten carbonate fuel cells and have included operation of a 10-cm square cell. Studies have continued on the development of electrolyte structures (LiAlO/sub 2/ and Li/sub 2/CO/sub 3/-K/sub 2/CO/sub 3/). This effort is being concentrated on the preparation of sintered LiAl0/sub 2/ as electrolyte support. Tape casting is presently under investigation as a method for producing green bodies to be sintered; this technique may be an improvement over cold pressing, which was used in the past to produce green bodies. The transition temperature for the ..beta..- to ..gamma..-LiAlO/sub 2/ allotropic transformation is being determined using differential thermal analysis. Work is continuing on the development of preoxidized, prelithiated NiO cathodes. Two techniques, one of which is simpler than the other, have been developed to fabricate plates of Li/sub 0/ /sub 05/Ni/sub 0/ /sub 95/O. In addition, electroless nickel plating is being investigated as a means of providing corrosion protection to structural hardware. To improve its cell testing capability, ANL has constructed a device for improved resistance measurements by the current-interruption technique.
