METHOD FOR MANUFACTURING SEALANT FOR SOLID ELECTROLYTE FUEL CELL

摘要

A method for preparing a sealing material for a solid electrolyte fuel cell is provided to allow a sealing material to be prepared simply and rapidly without using complex equipment and to lower a manufacturing cost. A method for preparing a sealing material for a solid electrolyte fuel cell comprises the steps of melting a mixture of barium oxide, silicon dioxide, boric acid and aluminum oxide to prepare frit; pulverizing the frit to make a crystalline glass particle having an average diameter of 5.4-20.0 micrometers; adding xylene and an acrylic resin to it as a dispersion medium in an amount of 50 wt% or less to the amount of frit to prepare a crystalline glass resin; and pouring the obtained glass resin into a mold of desired size and drying it. The amount of xylene is 2.2-14.9 wt%; and the amount of the acrylic resin is 16.3-32.6 wt%.
