A solid oxide fuel cell (SOFC) stack is disclosed. The SOFC may include an oxidizing agent flow path fluidly connecting a first oxidizing agent chamber and a second oxidizing agent chamber. The first oxidizing agent chamber may include an oxidizing agent supply pipe through which an oxidizing agent is flowed from an outside thereof. The second oxidizing agent chamber may perform a reduction reaction on the oxidizing agent received from the first oxidizing agent chamber. In operation, a fluid flows between the first and second oxidizing agent chambers, and may be provided to an outside of the second oxidizing agent chamber. Further, the structure of the flow path may allow heat to be conducted from the second oxidizing agent chamber.

Disclosed is a separator to seal a fuel chamber and a solid oxide fuel cell (SOFC) having the same. The separator for the SOFC includes a through hole to accommodate a unit cell and a groove formed in an inside surface of the through hole. According to the present invention, a groove where a sealing material is disposed is formed in a portion to be welded to stably form a filler metal. Further, a slanting part formed on the groove presses the sealing material in a direction to the unit cell to improve sealing efficiency.
