Advanced-fuel-cell development. Progress report, April-June 1981

This report describes fuel cell research and development activities at Argonne National Laboratory (ANL) during the period April through June 1981. These efforts have been directed toward (1) improving understanding of component behavior in molten carbonate fuel cells, and (2) developing alternative concepts for components. The principal focus has been on the development of sintered ..gamma..-LiAlO/sub 2/ electrolyte supports, stable NiO cathodes, and hydrogen diffusion barriers. Cell tests were performed to assess diffusion barriers and to study cathode voltage relaxation following current interruption.
