FUEL CELL SYSTEM WITH STRUCTURE FOR ENLARGING COMBUSTION LIMITATION OF COMBUSTOR

摘要

Disclosed is a fuel cell system with a structure for enlarging a combustion limitation. The fuel cell system comprises the following: a fuel cell; a reformer supplying hydrogen into the fuel cell through a hydrogen supply line; a combustor supplying heat to the reformer, and installed on an exhaust gas line connected to a fuel electrode of the fuel cell; and a moisture removal unit supplied to the exhaust gas line in between the fuel cell and the combustor. The moisture removal unit includes a cooling unit for cooling exhaust gas using a heat exchanging method, and a gas-water separator separating and discharging condensed water obtained by condensing the exhaust gas using the cooling unit.
