Abstract: A fuel cell system includes a fuel cell and a gas-liquid separator. The fuel cell includes an anode, a membrane, and a cathode. The gas-liquid separator includes a separator housing defining an internal cavity. The separator housing includes an inlet, an outlet, an outlet conduit, and a drain. The inlet is fluidly coupled to the fuel cell downstream from the anode. The outlet is fluidly coupled to an anode inlet of the anode. The outlet conduit extends axially into the internal cavity from a first axial end of the separator housing. The drain is disposed at a second axial end of the separator housing. The separator housing further defines an inlet passage that fluidly couples the inlet to the internal cavity and extends tangentially away form an interior surface of the separator housing.

Abstract: A gas-liquid separator comprises a housing comprising a first inlet structured to receive a blowby gas stream, the blowby gas stream having a first flow velocity, and a second inlet structured to a communicate a compressed gas into the housing, at least a portion of the second inlet disposed within the first inlet. An elastomeric nozzle is coupled to the first inlet and positioned around the second inlet, the elastomeric nozzle structured to combine the blowby gas stream with the compressed gas such that the compressed gas causes the blowby gas stream to flow at a second flow velocity that is greater than the first flow velocity. An impaction plate is disposed downstream of the elastomeric nozzle such that the blowby gas stream impacts the impaction plate and separates liquid and aerosol contained in the blowby gas stream.

Abstract: A filter assembly includes a filter head and a filter cartridge. The filter head includes a filter head coupling surface, a filter head outlet, a filter head inner wall, and a filter head outer wall. The filter head coupling surface defines a filter head opening. The filter head outlet is configured to provide a fluid. The filter head inner wall extends around the filter head outlet. The filter head outer wall extends around the filter head inner wall. The filter head inner wall and the filter head outer wall collectively define a filter head channel. The filter cartridge includes a filter cartridge shell and a filter element. The filter cartridge shell has a filter cartridge coupling surface that is configured to be coupled to the filter head coupling surface. The filter cartridge shell defines a filter cartridge opening.

Abstract: A rotating crankcase ventilation filter element comprises a motor comprising a stator and a rotor, and shaft. A first end of the shaft is coupled to the rotor and is configured to rotate in response to rotation of the rotor. A hub is disposed circumferentially around the shaft and coupled to the shaft such that the hub is rotationally locked with respect to the shaft. A filter media is disposed around the hub and secured thereto such that the filter media is rotationally locked with respect to the hub. The filter media is structured for axial flow of a gas through the filter media. A first end cap is disposed on a filter media first end, and a second end cap is disposed on a filter media second end of the filter media. The second end cap is coupled to the first end cap such that the filter media and the hub is secured therebetween.

Abstract: A water drain valve system structured to drain water from a fuel-water separator. The system includes a collection vessel structured to temporarily store water, a liquid level sensor structured to monitor a level of the temporarily stored water, a drainage port extending radially from the collection vessel and having a port inlet and a port outlet, and a valve assembly. The port inlet receives water to be drained from the collection vessel, the water flowing through the drainage port and exiting through the port outlet. The valve assembly is movable between a closed position in which the port outlet is closed, and an open position, in which the port outlet is open, to selectively allow water to be drained from the collection vessel. The valve assembly includes a solenoid coupled to a seal member, the seal member closing the port outlet in the closed position of the valve assembly.
