MSOFC development status
Objective is to develop materials and fabrication methodologies to develop a monolithic solid oxide fuel cell (MSOFC) system capable of meeting performance, life, and cost goals for coal-derived fuel applications. The program is aimed at fabrication and testing of a 100-W stack. The MSOFC is an all-ceramic structure in which cell components are configured in a compact, corrugated array; the electrolyte is zirconia, anode is Ni/Y{sub 2}O{sub 3}-ZrO{sub 2} cermet, cathode is doped LaMnO{sub 3}, and interconnects are doped LaCrO{sub 3}. Fabrication sequence is shown, along with electrochemical performance. Baseline anode formulation shrinks when exposed to hydrogen, causing cell curvature and stack delamination; new anode compositions are being developed. Sealants are being developed at Argonne. Thermal expansion mismatches need to be taken into account.
