FUEL CELL SYSTEM AND CONTROL METHOD THEREFOR

A fuel cell system comprises a compressor configured to supply the cathode gas to the fuel cell, an intercooler provided downstream of the compressor and configured to cool the cathode gas discharged from the compressor, a pressure regulating valve configured to adjust a pressure downstream of the intercooler, and a controller. The controller computes a first target pressure of the intercooler downstream pressure according to a target output of the fuel cell and computes a second target pressure of the intercooler downstream pressure according to the intercooler downstream temperature. Then, the controller sets smaller one of the first and second target pressures as a target pressure of the intercooler downstream pressure and controls the compressor and the pressure regulating valve according to the target pressure.
