High-temperature fuel cell research and development. Final technical status report, June 1977-September 1978
Description
An initial survey of the literature produced a list of ceramic materials with properties which made them potential candidates for use in molten-carbonate fuel cell tiles or electrodes. Seven of the materials in the original list were dropped from consideration because of unfavorable thermodynamic properties; four materials were set aside because of high cost, lack of availability, or fabrication difficulties. Thirteen compositions were tested statically at 1000 K in a Li/sub 2/CO/sub 3/-K/sub 2/CO/sub 3/ bath under a dry CO/sub 2/ atmosphere. Only four of the materials tested showed severe degradation reactions in the molten carbonate. A low-temperature process for … continued below

Description
An initial survey of the literature produced a list of ceramic materials with properties which made them potential candidates for use in molten-carbonate fuel cell tiles or electrodes. Seven of the materials in the original list were dropped from consideration because of unfavorable thermodynamic properties; four materials were set aside because of high cost, lack of availability, or fabrication difficulties. Thirteen compositions were tested statically at 1000 K in a Li/sub 2/CO/sub 3/-K/sub 2/CO/sub 3/ bath under a dry CO/sub 2/ atmosphere. Only four of the materials tested showed severe degradation reactions in the molten carbonate. A low-temperature process for forming small diameter, high-aspect ratio ceramic fibers for fuel cell use has been developed. A short-term program to initiate a computer study on the thermodynamic analysis of fuel cell materials was initiated at Montana State University. The report on this program is included as Appendix B. The MHD and high-temperature fuel cell literature was surveyed, and material properties were evaluated to identify MHD materials with potential use for fuel cell applications. A technology transfer report of these findings was prepared. This report is included as Appendix A. Laboratory facilities were established to conduct research on interfacial diffusion processes which could be detrimental to successful long-term operation of the solid-electrolyte fuel cell. A variety of physical and chemical techniques were examined for the preparation of high-density substituted LaCrO/sub 3/ which was to be one component of a diffusion couple with Y/sub 2/O/sub 3/-stabilized ZrO/sub 2/. Hydrolysis of a mixed metal-nitrate solution with urea produced the most reactive powder. A final theoretical density of almost 98% was attained in cold-pressed sintered discs of this material.
