PURPOSE: A method of manufacturing unit cell of solid oxide fuel cell is provided to simplify the manufacturing process of solid oxide fuel cell by bounding the film assembly of the fuel anode reactive layer/electrolyte layer on the porosity anode supporter, thereby saving time and expense. CONSTITUTION: A manufacturing method of unit cell of solid oxide fuel cell compromises steps of: forming the pre-sintered body of the anode supporter; manufacturing fuel electrode reactive layer sheet; manufacturing electrolyte layer sheet; manufacturing film assembly of the fuel electrode reactive layer sheet/electrolyte layer sheet; providing binder to the pre-sintered body above; laminating the combination above; co-sintering the laminated combination above; forming the air electrode layer on the electrolyte layer in the co-sintered body; and sintering the outcome above.
