Proposed are a gasket assembly and a fuel cell humidifier comprising the same which can be manufactured with improved productivity and can drastically reduce maintenance costs thereof. The gasket assembly according to an embodiment of the present disclosure is a gasket assembly for a fuel cell humidifier comprising a mid-casing, a cap fastened to the mid-casing, and at least one cartridge disposed in the mid-casing and receiving a plurality of hollow fiber membranes. The gasket assembly includes a packing part provided with a hole into which an end part of the cartridge is inserted, an edge part formed by being connected to the packing part, and a damping part formed on an outer peripheral surface of the cartridge.

Gasket assembly and fuel cell humidifier comprising same

The present invention relates to a humidifier for a fuel cell, the humidifier comprising: a humidifying module for humidifying a dry gas, supplied from the outside, by using a wet gas discharged from a fuel cell stack; a first cap coupled to one end of the humidifying module; and a second cap coupled to the other end of the humidifying module. The humidifying module includes: a mid-case, both ends of which are open; and at least one cartridge that is located inside the mid-case and includes a plurality of hollow fiber membranes. The distance between a second gas inlet and a second gas outlet, which are formed in an inner case of the cartridge, is greater than the distance between a first gas inlet and a first gas outlet, which are formed in the mid-case.

Humidifier for fuel cell

Disclosed are: a fuel cell humidifier capable of reliably preventing a gas leak due to repeated operating and stopping of a fuel cell and capable of being manufactured with relatively low manufacturing costs and high productivity; and a manufacturing method therefor. The fuel cell humidifier of the present invention includes a humidifying module and caps coupled to both ends of the humidifying module, respectively, wherein: the humidifying module includes a mid-case, a plurality of hollow fiber membranes in the mid-case, a fixed layer in which the ends of the hollow fiber membranes are potted, and a composite gasket having a groove into which the end of the mid-case is fitted; the composite gasket includes an inner body, an outer body, and a connecting body provided therebetween and formed of a first material; and at least a portion of the inner body is adhered to the fixed layer and is formed of a second material that is different from the first material.

Fuel cell humidifier and manufacturing method therefor

The present invention relates to a membrane humidifier for a fuel cell, which can prevent a decrease in humidification efficiency due to a pressure difference between the inside and outside of a membrane humidifier, the membrane humidifier for a fuel cell, according to an embodiment of the present invention, comprising: a middle case having a module insertion part inside; a cap case coupled to the middle case; a hollow fiber membrane module inserted to the module insertion part; and a pressure buffer part between the inner wall of the middle case and the module insertion part.

Membrane humidifier for fuel cell

The present disclosure relates to a gasket assembly that can be manufactured with improved productivity and can dramatically reduce maintenance costs, and a fuel cell humidifier including the same. A gasket assembly according to an embodiment of the present disclosure is provided for a fuel cell humidifier including a mid-case, a cap fastened to the mid-case, and at least one cartridge disposed in the mid-case and accommodating a plurality of hollow fiber membranes.

Gasket assembly and fuel cell humidifier including same

The present invention relates to a membrane humidifier for a fuel cell capable of simplifying a fuel cell system and miniaturizing the fuel cell system by performing humidification by moisture exchange and cooling by heat exchange in one membrane humidifier, and a fuel cell system comprising same. The membrane humidifier for a fuel cell of the present invention comprises both a humidification module and a heat exchange module in a housing part, and distributes a first fluid to the humidification module and the heat exchange module at a variable distribution ratio.

Membrane humidifier for fuel cell, and fuel cell system comprising same

Disclosed is a SRAM cell and a method of manufacturing the same. The SRAM cell comprises: a pair of access devices; a pair of pull-up devices; a pair of pull-down devices; and at least one metal plate formed on metal interconnection lines in contact with a substrate, having a dielectric film interposed between the metal plate and the metal interconnection lines, so as to increase a cell capacitance, thereby reducing a soft error rate. Herein, one metal plate may be included in each cell. In this case, the metal plate overlaps with a first one of metal interconnection lines of a node side and a node bar side, while being in contact with a second one of the metal interconnection lines of the node side and the node bar side. Also, two metal plates may be included in each cell. In this case, the metal plates overlap, respectively, with one metal interconnection line of metal interconnection lines of a node side and a node bar side, while being in contact with another metal interconnection line of the node side or the node bar side, respectively. Therefore, capacitance is additionally formed to increase cell capacitance, so that variation of the electric potentials of cell nodes, which is caused by generated electrons, is prevented, and thereby soft error can be efficiently reduced.
