Advanced Fuel Cell Development Progress Report: July-September 1981

The report describes fuel cell research and development activities at Argonne National Laboratory (ANL) during the period July through September 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 cathodes fabricated form NiO, sintered ..gamma..-LiAlO/sub 2/ electrolyte supports, and diffusion barriers to prevent gas cross-leakage. Cell tests were performed to assess variables affecting diffusion and to study cathode potential relaxation following current interruption.
