Title: Filter device

Abstract: A filter device disposed in a moist fluid passage of the fuel cell system includes a fluid introducing path which introduces a fluid that flows in the moist fluid passage, a filter to permeate the fluid introduced from the fluid introducing path and remove foreign matter in the fluid, a fluid discharge path which discharges a fluid that passed the filter, and a rotating driving mechanism, connected with the filter, that rotates the filter so that substances that adheres to the filter are removed by the centrifugal force. In the filter device, water does not adhere to and does not remain in the filter. When leaving the system under the low temperature after the system stops, blockage by freezing the filter can surely be prevented. The complex control and the heat source such as a heater for defrost is unnecessary. Thus, a cheap and compact filter device can be provided.
