Abstract: Provided is a manufacturing method of composite powder enabling to manufacture an electrode for a solid oxide fuel cell in a mesoporous structure with a low temperature sintering. The manufacturing method of composite powder according to the present invention comprises that a surfactant ethanol solution in which Pluronic^R F127 surfactant is added to ethanol is formed, and that a sol solution is formed by mixing a metallic salt of nickel, a metallic salt of gadolinium and a metallic salt of cerium in the surfactant ethanol solution. The sol solution is synthesized to a gel state by using the hydrothermal synthesis at 100°C or less, and dried powder is obtained by drying the synthesized gel state solution. Then, calcinated powder is obtained by calcinating the dried powder. [Reference numerals] (AA) Add F127 surfactant in aqueous hydrochloric acid and ethanol;(BB) Material mixing (Cerium nitrate hexahydrate + Gadolinium nitrate hexahydrate +Nickel nitrate hexahydrate);(CC) Stiring;(DD) Gelation (Stirring at 80°C for 1 hour);(EE) Hydrothermal synthesis (80°C for 7 days);(S1) Mixing;(S2) Synthesis;(S3) Dry - Heating at 70°C in air;(S4) Calcination - 450-650°C for 2 hours at the atmosphere of air in furnace
