Abstract

The present invention provides a fuel cell system, which reduces the temperature of exhaust gas discharged from a fuel cell stack to a humidifier to increase the humidity thereof when the fuel cell stack operates at high temperature and high power, and thus improves the humidification performance for air as an oxidant in the humidifier and improves the performance of the fuel cell stack. For this purpose, the present invention provides a fuel cell system in which an intercooler is installed in an exhaust gas pipe, which connects a cathode outlet of the fuel cell stack and the humidifier, to cool the exhaust gas as a water supply source of the humidifier such that the intercooler reduces the temperature of the exhaust gas and, at the same time, increase the humidity thereof, thus improving humidification performance for air as an oxidant in the humidifier.
