Abstract
A fuel cell system capable of suppressing noise caused by backflow of air when a compressor stops. Also, there is provided a fuel cell vehicle provided with this fuel cell system. A fuel cell system includes a fuel cell and a compressor that compresses air taken in from outside and supplies compressed air to the fuel cell. Operation of the compressor is stopped after a pressure difference between an upstream side and a downstream side of the compressor has become equal to or smaller than a predetermined value by using a control unit. In this case, the predetermined value can be a pressure difference corresponding to a predetermined noise level.
