The present invention relates to a cartridge of a fuel cell humidifier and the fuel cell humidifier, the cartridge comprising: an inner case to be inserted into a middle case of the fuel cell humidifier for humidifying dry gas supplied from the outside using wet gas discharged from a fuel cell stack; a plurality of hollow-fiber membranes accommodated inside the inner case; a first potting part which is coupled to the inner case and which fixes one side of each of the hollow-fiber membranes; a second potting part which is coupled to the the inner case and which fixes the other sides of the hollow-fiber membranes; and a link member for connecting the inner case to the middle case so that the middle case and the inner case are linked so as to move according to the pressure of the wet gas positioned inside the middle case.

The present disclosure relates to devices and processes for the production of hollow fiber membrane bundles. The bundles are used for the manufacture of filtration and/or diffusion devices, e.g., capillary dialyzers.

A fuel cell humidifier may completely or substantially completely prevent condensate water from entering a running fuel cell stack. The fuel cell humidifier includes a housing; a plurality of hollow fiber membranes arranged in the housing; a cap which is coupled to one end of the housing and has an air discharge port for supplying humidified air to the fuel cell stack; and a bypass tube for transferring condensate water generated from the humidified air to an interior space of the housing through which a discharge gas flows, wherein a first end of the bypass tube is disposed inside the air discharge port, and the bypass tube is in fluid communication with the interior space of the housing through a second end of the bypass tube.

Provided is a hollow fiber membrane module that exhibits excellent durability even when a chemical such as a radical polymerizable compound is used for a separation or mixing process. Also provided is a method for producing the hollow fiber membrane module in a highly productive manner. More specifically, there is provided a hollow fiber membrane module at least including a tubular body, a cap, a hollow fiber membrane, and an end seal portion, wherein at least a liquid contacting portion of the end seal portion is sealed with a cured product of a curable resin composition including an epoxy resin, and wherein the epoxy resin includes a polyglycidyl ether of a polycondensate of an aromatic compound containing a phenolic hydroxyl group and an aromatic compound containing a formyl group and a phenolic hydroxyl group, and there is provided a method for producing the module.

The invention relates to a device for removing a gas from an aqueous liquid, particularly a blood liquid, comprising a first compartment permeated by the aqueous liquid during operation of the device; a second compartment permeated by a purging gas during operation of the device, the first compartment and the second compartment being separated from each other by a semipermeable membrane; and a third compartment permeated by a liquid proton donor during operation of device, said proton donor being an organic or inorganic acid, the first compartment and the third compartment being separated from each other by a membrane permeable to ions, and the membrane permeable to ions comprising at least one cation conductor.

A degasification system includes a degasification unit in which a plurality of degasification modules degasifying a liquid are connected, wherein the degasification unit has a connection supply pipe which connects the liquid supply paths of the plurality of degasification modules in series and in which openings through which the liquid passes are formed at positions corresponding to the plurality of degasification modules such that the liquid is supplied to the hollow fiber membrane bundles of the plurality of degasification modules in parallel, and wherein the degasification unit is configured such that a pressure loss of the liquid from a supply port of the connection supply pipe through which the liquid is supplied to the discharge ports of a downstream side degasification module is larger than a pressure loss of the liquid from the supply port to the discharge ports of an upstream side degasification module.

A hollow fiber membrane module includes: a first hollow fiber membrane whose sieving coefficient for dextran having a molecular weight of not less than 300 kDa nor more than 1000 kDa is not less than 0.12 nor more than 0.28, wherein the first hollow fiber membrane adsorbs endotoxins.

A fluid filtration system includes a fluid storage vessel such as a bioreactor, a filter housing including a filter element disposed therein, a pump coupled between the fluid storage vessel and the filter housing, and a flow diverter disposed between the pump and the filter housing. The pump is configured to move fluid from the fluid storage vessel through the filter element, and the flow diverter is configured for selectively directing fluid received from the pump to the first or second end of the filter housing. In a first mode of operation, the flow diverter directs flow through the filter housing in a first direction, while in a second mode of operation, the flow diverter directs flow through the filter housing in a second direction opposite the first direction.

A blood processing apparatus includes an optional heat exchanger and a gas exchanger disposed within a housing. In some instances, the gas exchanger can include a screen filter spirally wound into the gas exchanger such that blood passing through the gas exchanger passes through the screen filter and is filtered by the spirally wound screen filter a plurality of times.
