Abstract: A humidifier having a housing that extends along an axial direction, the housing having a first inlet, a first outlet, a second inlet and a second outlet, and a membrane unit being arranged in the interior of the housing. The first inlet and the first outlet are in flow connection with each other by means of a first flow path, and the second inlet and the second outlet are in flow connection with each other by a second flow path. The membrane unit is cylindrical and has a plurality of hollow fiber membranes arranged side by side. The membrane unit is outwardly surrounded at least in part by a first chamber, and the first chamber is outwardly surrounded at least in part by a second chamber separate from the first chamber. The first chamber and the second chamber are in flow connection with each other via one or more throttle slots.

Abstract: The present invention relates to a fuel cell membrane humidifier capable of improving humidification efficiency by performing two-stage humidification, and a fuel cell system comprising same. A fuel cell membrane humidifier according to an embodiment of the present invention comprises: a dry air supply means; a fuel cell membrane humidifier which performs two-stage humidification on the dry air supplied from the dry air supply means; a fuel cell stack for generating energy and humid exhaust gas by reacting the humidified air supplied from the fuel cell membrane humidifier with hydrogen; and a bypass flow path for bypassing a portion of the exhaust gas generated in the fuel cell stack. The fuel cell membrane humidifier comprises: a mid-case; a cap which is fastened with the mid-case and has a bypass inlet connected to the bypass flow path; a mixing humidifier which performs mixed humidification by mixing the dry air introduced through the cap and the exhaust gas introduced through the bypass inlet; and at least one cartridge which is disposed in the mid-case and accommodates a plurality of hollow fiber membranes that perform moisture exchange.

Abstract: A filter includes a housing having an interior space, in which the housing has at least one opening end. The filter further includes a membrane disposed within the housing that has a length that extends along a length direction of the housing, and a baffle provided at least in the interior space of the housing. The baffle includes at least two baffle partitions that extend along at least a portion of the length of the membrane to divide the interior space of the housing into at least a first portion and a second portion so that when a fluid is supplied to the filter, the fluid is directed to first flow in the first portion and then to the second portion.
