20100285394HYBRID SEALING COMPOSITE FOR FLAT SOLID OXIDE FUEL CELL STACK - The present invention provides a hybrid composite sealant, as a sealing material for a planar type solid oxide fuel cell stack, having a matrix of a glass composition, wherein a surface layer reinforced with platelet reinforcement particles is laminated on either one or both surfaces of an inner layer reinforced with fibrous reinforcement particles. Accordingly, by applying the composite sealant of the present invention to the solid oxide fuel cell stack, excellent gas-tightness of the stack can be obtained even under low coupling pressure, thermal cycling durability can be enhanced due to low coupling strength with a contact surface of an object to be sealed, stack disassembly and maintenance can be facilitated when parts within the stack are disabled, and stack stability as well as stack performance can be maintained under a pressurized operation condition where pressure differentials between the inside and outside of the stack reach to 5 atmospheric pressures (0.5 MPa).11-11-2010
20100331165SEALING COMPOSITE FOR FLAT SOLID OXIDE FUEL CELL STACK HAVING HIGH FRACTURE RESISTANCE AND THE FABRICATION METHOD THEREOF - A composite sealant of the present invention increases a fracture toughness of glass which has an excellent gas tightness but has a low fracture resistance, to enhance the thermal cycle stability while maintaining the gas tightness of a stack. For this, alpha-alumina fiber particles, alpha-alumina granular particles, and metallic particles are mixed and added to a glass matrix for remarkably increasing the fracture toughness from 0.5 MPa·m05 to 6 MPa·m°'5 through the multiple effects of crack deflection and crack bridging by the fiber and granular particles, and effects of crack arresting and plastic deformation by the metallic particles. When using the high fracture toughness composite sealant of the present invention, since the gas tightness and the stability of the stack can be maintained even when there is a thermal stress produced by a non-uniform temperature distribution or a thermal cycle condition in the stack, increasing the fracture toughness of the composite sealant works as the most important factor for enhancing the reliability of a large-area stack.12-30-2010
