Abstract
An object of the present invention is to provide a fuel cell system in which a noise and a vibration of a compressor can be suppressed. In order to achieve the above object, the present invention provides a fuel cell system including a fuel cell; a compressor for supplying an oxidant gas to the fuel cell, having a first rotational speed region within which as a rotational speed increases, a noise becomes greater than a predetermined value, and a second rotational speed region within which as the rotational speed increases, the noise becomes equal to or less than the predetermined value; and a compressor controller for controlling the compressor by calculating a command rotational speed for commanding the compressor based on a required amount of power generation.
