Fuel cell system

Provided is a fuel cell system capable of suppressing the movement of an operating point of a compressor between a surge region and a non-surge region to reduce operation sounds and vibrations, the fuel cell system including at least: a fuel cell; a compressor; a dry state estimation part to estimate a dry state of the fuel cell; and a pressure target control part to control a pressure target, wherein the pressure target control part is capable of executing at least rise control and lower control, the rise control and the lower control being such that an operating point of the compressor is positioned outside a surge region, a current pressure target is corrected to the value same as a last pressure target if the current pressure target is lower (higher) than the last pressure target when the rise control (lower control) is being carried out.
