1. A fuel cell system comprising:a fuel cell having at least an air inlet and an exhaust gas line; a gas compressor connected to an air-supply line through which process air is supplied from said gas compressor into said fuel cell, said gas compressor having at least a compression chamber, a suction port, a delivery port and a water-supply port; a recovery unit arranged in said exhaust gas line through which an exhaust gas, containing therein produced water, is discharged from said fuel cell; a liquid-gas separating unit arranged in said exhaust gas line between said fuel cell and said recovery unit for separating said produced water from said exhaust gas, said liquid-gas separating unit having a water storing vessel for storing said produced water separated from said exhaust gas; a water-supply line connecting between said water storing vessel of said liquid-gas separating unit and said water-supply port of said gas compressor, wherein said produced water is delivered from said water storing vessel through said water supply line to said water supply port by applying the pressure of said exhaust gas to said produced water in said water storing vessel.
