SOLID OXIDE FUEL CELL SYSTEM HAVING COATING LAYER FORMED THEREON

摘要

The main purpose of the present invention is to provide a solid oxide fuel cell system having a coating layer formed thereon, which prevents oxidation due to high temperatures and volatilization of chrome due to high temperatures by forming a coating layer having excellent high temperature durability on the surfaces of components and pipes, arranged inside a high temperature box of a solid oxide fuel cell. The solid oxide fuel cell system having a coating layer formed thereon, of the present invention which is for achieving the aforesaid purpose, comprises: a high temperature box; a burner, a heat exchanger, and a stack, which are arranged inside the high temperature box; a plurality of pipes, which are gas passages between the burner, heat exchanger, and stack; and a coating layer, which is formed on the surface of the burner, heat exchanger, or pipes and thereby prevents oxidation due to high temperatures or volatilization of chrome due to high temperatures.
