摘要:
Disclosed is a method and device for producing a membrane module used in a membrane humidifier for humidifying air in a polymer fuel cell, in which a small amount of hollow fiber membranes are disposed in the center of the membrane module and a larger amount of hollow fiber membranes are disposed toward the edge based on the design of a potting cap. Dry air introduced from an air blower into the membrane can be distributed to the edge where the larger amount of hollow fiber membranes are disposed, thereby maintaining uniform humidification performance over the entire hollow fiber membranes.

A membrane humidifier is provided for a fuel cell. The membrane humidifier of the present invention includes a hollow housing, a joint member, a plurality of internal partition modules, and a plurality of hollow fiber membrane bundles. The hollow housing has a humid air inlet formed at one end thereof and a humid air outlet formed at the other end thereof. The joint member is formed integrally with an inner circumferential surface of the hollow housing. The plurality of internal partition modules are coupled to the joint member and arranged adjacent to each other in the hollow housing, and have a plurality of humid air guiding apertures passing therethrough. The plurality of hollow fiber membrane bundles are disposed in the plurality of internal partition modules, respectively.

A humidification system using an injector for a fuel cell stack includes: a fuel cell separator including a reaction flow field, and an air inlet port and an air outlet port formed at a front portion and an end portion of the reaction flow field, respectively; a humidification chamber provided at a part of or the whole length of the front portion of the reaction flow field of the separator; and an injector mounted at a starting point of the humidification chamber to inject a mixture of water and air into the humidification chamber. With the system, humidification efficiency can be improved and/or maximized without an increase in the volume of the fuel cell stack.
摘要:
Disclosed is a membrane humidifier for a fuel cell, which uniformly humidifies entire hollow fiber membranes from an outer side to a central portion of an interior of the membrane humidifier to improve the distribution of wet air and dry air, thereby improving a humidification performance. The membrane humidifier for the fuel cell includes a hollow upper case including first wet air inlet apertures and first wet air outlet apertures and a membrane module assembly including a plurality of unit membrane modules received lengthwise within the upper case along the flow direction of dry air.

摘要:
The present invention provides a humidification system with membranes of different species, in which a material having a high humidification performance and capable of being swollen with water is arranged in the center of a hollow fiber membrane bundle disposed in a hollow fiber membrane module and a material that is not swollen with water is disposed on the outside thereof. Accordingly, using the humidification system of the invention, it is possible to provide the same level of humidification performance as the existing humidification system, manufacture the humidification system at low cost, and solve various problems such as a flooding phenomenon of a fuel cell stack and an increase in load on an air blower.
