The present invention relates to a method for pretreating a solid oxide fuel cell. The method according to an embodiment of the present invention relates to a method for pretreating a solid oxide fuel cell including an anode provided with an anode gas, a cathode electrode provided with a cathode gas, and a stack unit in which unit cells are continuously stacked. The method comprises: an organic material removing step of injecting an organic material removing gas to the stack unit according to a predetermined removing pressure condition when an organic material removing signal is inputted; an organic material inspecting step of determining whether an organic material is completely removed by using a measured output voltage of the unit cell when the stack unit reaches a predetermined target removing temperature; a sealing material dissolving step of injecting a dissolved gas to the stack unit according to a predetermined dissolving pressure condition when a sealing material dissolving signal is inputted, and heating the stack unit according to a predetermined dissolving and heating condition; and a sealing re-inspecting step of determining completion of dissolving of the sealing material by using a measured output voltage of the unit cell and internal pressure of the stack unit when the stack unit reaches a predetermined target dissolving temperature. |
