    摘要: 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.

    摘要: The present invention discloses a paste for screen printing which is used in a process of fabricating an anode functional layer, an electrolyte layer and a cathode layer of an anode-supported solid oxide fuel cell. The paste for the solid oxide fuel cell contains raw material powder of each layer, ethyl cellulose which is a binder, alpha terpineol which is a solvent, and an alcoholic solvent which has solubility to a thermosetting binder contained in an anode support and which is added by 0.5 to 20 wt % of alpha terpineol as an additional solvent. The present invention also discloses a fabricating method of an anode-supported solid oxide fuel cell which forms each layer of the fuel cell by screen printing by using the paste. According to the present invention, in the highly efficient pore structure anode support fabricated by thermosetting molding, the composition of the paste for screen printing is controlled to improve weftability, and the movement of the elements is restricted by curing, thereby reducing surface defects of the layers and interfacial defects between the layers in fabrication and improving the interface strength. As a result, the high performance large area solid oxide fuel cell can be economically and efficiently fabricated, and reliability of the product can be remarkably improved.
