A suitable sealant must form strong, dense bonds with SOFC components, be compatible, be stable at 1000{degrees}C in SOFC operating environment (H{sub 2} and H{sub 2}O on anode side, O{sub 2} on cathode side), and be electrically insulating. Two types of sealants are being developed: Rigid (Mg ammonium phosphate cement) for the cell edge, and compliant (borate-based glass-ceramic) for stack-to-manifold joining. Testing of both is reported. Shrinkage of the rigid sealant needs to be reduced. Further testing is underway.
