Device for adjusting hollow fiber membrane density for humidification device of fuel cell

摘要

Disclosed is a device for adjusting humidification gas of a membrane humidification device of a fuel cell. In particular, the device is adapted to induce changes in differential pressure and velocity of the wet air for each division module and to improve the humidification efficiency by sequentially mounting the division modules divided into various numbers to the interior of a housing of the membrane humidification device, thereby adjusting the density of the hollow fiber membrane filled in each division module.

主权项

1. A device for adjusting a hollow fiber membrane density for a membrane humidification device of a fuel cell system, comprising:
a hollow housing in which a dry air supply port and a discharge port for discharging the humidified dry air are formed on both sides, a wet air inlet is formed at a first end portion, and a wet air outlet is formed at a second end portion; a plurality of division modules that contact wet air and are mounted to an interior of the housing; and hollow fiber membranes disposed in an interior of each of the division modules, wherein the division modules are fixedly mounted to an inner space of the wet air inlet side of the housing, an inner space of the wet air outlet side, and a space between the wet air inlet and outlet and each of division modules is divided into various numbers of sections.
