    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 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.
