Advanced-fuel-cell development. Progress report, October-December 1980
This report describes the fuel cell research and development activities at Argonne National Laboratory (ANL) during the period October through December 1980. These efforts have been directed toward (1) developing alternative concepts for components of molten carbonate fuel cells, and (2) improving understanding of component behavior. The principal focus has been on development of ..gamma..-LiAlO/sub 2/ sinters as electrolyte structures. Green bodies were prepared by tape casting and then sintering ..beta..-LiAlO/sub 2/; this has produced ..gamma..-LiAlO/sub 2/ sinters of 69% porosity. In addition, a cathode prepared by sintering lithiated nickel oxide was tested in a 10-cm square cell. Although the bimodal pore distribution in the cathode successfully provided agglomerates flooded with electrolyte and open pores for gas passage, the cathode dimensional variations prevented good contact with the tile, which was stiffer than normal. The tile was prepared using an improved synthesis procedure, which resulted in high-surface-area ..gamma..-LiAlO/sub 2/ particles; but, because the carbonate content was the same as used in previous tests, the tile was less compliant. The cell had excellent seals because dimensional changes associated with in situ cathode reactions were eliminated.
