Description

This report describes advanced fuel cell research and development activities at Argonne National Laboratory (ANL) during the period July--September 1978. These efforts have been directed toward understanding and improving the components of molten-carbonate-electrolyte fuel cells operated at temperatures near 925 K. The primary focus of this work has been the development of electrolyte structures that have good electrolyte retention and mechanical properties as well as long term stability, and on developing methods of synthesis amenable to mass production. The characterization of these structures and their stability is an integral part of this effort. Synthesis studies have concentrated on the use ... continued below

Description

This report describes advanced fuel cell research and development activities at Argonne National Laboratory (ANL) during the period July--September 1978. These efforts have been directed toward understanding and improving the components of molten-carbonate-electrolyte fuel cells operated at temperatures near 925 K. The primary focus of this work has been the development of electrolyte structures that have good electrolyte retention and mechanical properties as well as long term stability, and on developing methods of synthesis amenable to mass production. The characterization of these structures and their stability is an integral part of this effort. Synthesis studies have concentrated on the use of low-cost starting material to synthesize ..gamma..-LiAlO/sub 2/, the most stable allotrope of LiAlO/sub 2/ for the fuel cell conditions. Thermal stability and thermomechanical tests were performed on electrolyte mixtures to determine the effect of cell operating conditions on electrolyte tile longevity. A square cell (10.6 cm) with an electrolyte tile containing ..gamma..-LiAlO/sub 2/ was tested. This tile was reinforced by a wire screen. Post-test examination of this cell after 1000 h of operation showed that the reinforced tile was considerably stronger than un-reinforced tiles. Future cells will utilize tiles with metal screen reinforcement.
