The tubesheet has an annular structure that encapsulates the hollow fiber membranes and the porous support tube at the first end of the bundle but which does not completely block a bore of the porous support tube, wherein the collection tube has a plurality of orifices formed therein at least at positions adjacent the nub.

A method of manufacturing a stack plate of a humidifier, comprises providing a semipermeable membrane that is airtight but permeable to moisture, depositing a plastic layer forming a plastic frame to a first side of the semipermeable membrane so that the semipermeable membrane is arranged over a fluid passage of the plastic frame, and depositing a gasket layer forming a gasket to a second side of the semipermeable membrane, the gasket being for sealing the stack plate against another stack plate, and the second side opposing the first side at least in some areas where the semipermeable membrane is supported by the plastic frame on the first side.

The present disclosure is directed to a membrane vessel, the membrane vessel comprising: a cylindrical tube for holding a membrane element, the cylindrical tube having a first end and a second end; at least one flared end of the cylindrical tube wherein the tube flares outward at an angle from the end of the cylindrical tube; a cap configured to fit into the end of the cylindrical tube, the cap comprising an inclined distal perimeter surface configured to contact the inner surface of the flared tube.

A ceramic membrane filtration assembly comprising a membrane assembly extending from a first membrane assembly end to a second membrane assembly end, where the membrane assembly is defined by a membrane assembly length, the membrane assembly including at least one membrane. At least one of the membranes have channels therein, and at least one channel has channel ends. The filtration assembly further includes at least one sealing device coupled with the membrane assembly adjacent to at least one of the first and second membrane assembly ends, where the sealing device has an inner and outer perimeter. The sealing device has a sealing feature disposed along the outer perimeter, and the inner perimeter of the sealing device is sealed with a portion of the membrane assembly.

A case has a first pipe and a second pipe. In the case, a holding member that holds a plurality of hollow fiber membranes is provided. The holding member includes a first plate-shaped portion and a second plate-shaped portion provided to sandwich the plurality of hollow fiber membranes and a connection portion connecting the plate-shaped portions. A passage passing from the first pipe to the first plate-shaped portion is formed between the first plate-shaped portion and the case and a passage passing from the second pipe to the second plate-shaped portion is formed between the second plate-shaped portion and the case.

The present disclosure relates to a fuel cell membrane humidifier in which a gap between an inner case and a mid-case constituting a cartridge is sealed to prevent off-gas from being bypassed. The disclosed fuel cell membrane humidifier includes: a mid-case having a partition wall partitioning an internal space; a first cap fastened to one side of the mid-case; a second cap fastened to other side of the mid-case; an inner case disposed in the mid-case and configured to accommodate a plurality of hollow fiber membranes therein; a rib protruding from one side of the inner case and coming into contact with one surface of the partition wall; a hook protruding from other side of the inner case and coming into contact with other surface of the partition wall; a first gasket disposed between the first cap and the inner case and configured to transmit fastening force between the first cap and the mid-case to the rib; and a second gasket disposed between the second cap and the inner case and configured to transmit fastening force between the second cap and the mid-case to the hook.
