SOLID OXIDE FUEL CELL SYSTEM WITH IMPROVED THERMAL EFFICIENCY, AND SOLID OXIDE FUEL CELL SYSTEM HEATED BY HIGH-TEMPERATURE GAS

摘要

Disclosed is a solid oxide fuel cell system with enhanced thermal efficiency. Accordingly, provided is a solid oxide fuel cell system with enhanced thermal efficiency, which is capable of heating and using fuel, air, or water supplied to a hot box at a room temperature by a heat exchanger in the hot box and minimizing heat discharged to the outside of the hot box.
