FUEL CELL SYSTEM

PROBLEM TO BE SOLVED: To provide a water recovery system with small size and good mounting performance in a fuel cell system which condenses and recovers water contained in the exhaust gas from a fuel cell and supplies the recovered water to the fuel cell. SOLUTION: The fuel cell system includes the fuel cell 1 which obtains electric power by reacting electrochemically an oxidizer gas and a fuel gas, a discharge passage 21 of the oxidizer gas exhausted from the fuel cell 1, a gas liquid separator 26 installed in the discharge passage 21, and a pressurizing means which increases the pressure of the oxidizer gas supplied to the gas liquid separator 26 more than the pressure of the oxidizer gas inside the fuel cell 1. Since the moisture contained in the oxidizer gas is condensed by the pressurizing means, a small-size water recovery system can be provided without using a bulky condenser as a condensing means.
