MANUFACTURING METHOD OF SUPPORT FOR SOLID OXIDE FUEL CELL

摘要

The present invention relates to a manufacturing method of supporter for solid oxide type fuel cell which includes the followings: a step of preparing and mixing magnesia having law BET of the range of 0.1-40 m^2/g, and a beginning raw material which includes 20-100 parts by weight of more than one material selected from spinel (MgAl2O4) and agrain (Al2O3) base on the 100 parts by weight of the magnesia; a step of shaping and drying the mixed outcome in order to have a flat tube shape which includes a fuel supply path; a step of plasticizing the shaped body at the temperature of 1400-1800°C. According to the present invention, the porous solid oxide type fuel cell supporter which is inexpensive, has an excellent mechanical strength and heat-resisting property, has thermal expansion coefficient which is similar to the quality of electrolyte is manufactured.
