FILTER DEVICE, CONTROL VALVE COMPRISING THE FILTER DEVICE, AND FUEL CELL SYSTEM

摘要

[Problem];The object of the invention is to provide the filter device disposed in the moist fluid passage of the fuel cell system in that, water is not adhered and never remains in the filter and when leaving it under the low temperature after the system stops, blockage by freezing the filter can surely be prevented, and the complex control and the heat source such as heaters for the decompression as conventional is unnecessary, and the filter device is cheap and compact.;[Resolution Approach];A filter device 50 disposed on a moist fluid passage of a system including moisture in the fluid, the filter device comprising:
a fluid introducing path 58 in which fluid that flows on the moist fluid passage is introduced into a filter room 60 from below filter room 60, a filter member 66 in which the fluid introduced from the fluid introducing path 58 into a filter room 60 is permeated and the foreign matter in the fluid is removed,a filter 62 placed in the filter room 60, a water pooling portion 72 disposed under the filter 62, anda fluid discharge path 70 in which the fluid that passed the filter 62 is discharged.

1. A filter device disposed on a moist fluid passage of a system including moisture in the fluid, the filter device comprising:
a fluid introducing path in which fluid that flows on the moist fluid passage is introduced into a filter room from below filter room, a filter member in which the fluid introduced from the fluid introducing path into a filter room is permeated and the foreign matter in the fluid is removed, a filter placed in the filter room,a water pooling portion, which is provided on the lower position than the filter member on sidewall side of the filter room bottom on the periphery of the filter, or
a water pooling portion, which is provided on the lower position than the filter member of the filter, or a water pooling portion, which is on both positions, a fluid discharge path in which the fluid that passed the filter is discharged, wherein, as the water level of the water pooling portion becomes a water level which is arrived to the filter member of the filter, a gap size J1 between the filter and the sidewall of the filter room is designed to become a predetermined size.
