    Abstract: 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).

    Abstract: 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.
