A BOP SYSTEM OF SOLID OXIDE FUEL CELL, A STACK MODULE OF SOLID OXIDE FUEL CELL INCLUDING IT AND AN OPERATING METHOD TO INCREASE THERMAL EFFICIENCY THEREOF

摘要

A balance of plant (BOP) system of solid oxide fuel cell according to the present invention has purposes for increasing thermal efficiency, extensity of devices and manufacturing efficiency and includes a burner, a reformer, a steamer and a thermal exchanger. Flame and combustion gas generated form the burner are directly transmitted to the reformer and the steamer on the upper layer of the burner by consecutively stacking the burner, the reformer, steamer in sequence from the bottom. The thermal exchanger receives exhaust gas from the steamer, which preheats process air supplied from an air electrode of the stack.
