    Abstract: PURPOSE: A fuel cell interconnector and a method for manufacturing the same are provided to improve the performance of a fuel cell by forming a chromium manganese oxide-based spinel oxide layer on ferrite-based steel. CONSTITUTION: A method for manufacturing a fuel cell interconnector includes the following: Ferrite-based steel for a fuel cell interconnector is prepared. A surface deformed layer is formed on the surface of the ferrite-based steel. A Cr_2MnO_4-based spinel oxide layer is formed on the surface deformed layer by implementing a thermal treatment process at the driving temperature of a solid oxide-based fuel cell.
