Disclosed is a method for manufacturing a supporting structure for a solid electrolyte fuel cell having uniform internal micro structure and excellent mechanical intensity. The method comprises the steps of: preparing raw material powder where nickel oxide (NiO) and yttria-stabilized zirconia (YSZ) are mixed; forming mixed powder by mixing a pore forming agent with the raw material powder; obtaining dried powder by spraying and drying slurry of the mixed powder; and forming and sintering the dried powder, wherein either an antifoamer or a bonding agent can be added to the mixed powder.
