FABRICATING METHOD OF SEALANT FOR SOLID OXIDE FUEL CELL

摘要

A method for manufacturing a sealant for a solid oxide fuel cell is provided to produce a sealant which is applicable to unit cell and stack of a flat type solid electrolyte fuel cell, and has no gas leakage and excellent electrical insulation. A method for manufacturing a sealant for a solid oxide fuel cell comprises the steps of: melting a barium oxide(BaO)-silicon oxide(SiO2)-boric acid(B2O3)-aluminium oxide(Al2O3) mixture to prepare frit; pulverizing the frit with crystallized glass particles with average particle diameter 5.4~20.0 mm; adding xylene 2.2~14.9 weight% and acrylic resin 16.3~32.6 weight% as a dispersing medium to prepare crystallized glass resin; and pouring the glass resin in the desired mould and drying the resin to prepare the sealant.
