Abstract: Disclosed in a hybrid humidifier for a fuel cell that has a plurality of humidifying tubes, each of the tubes defining thereon a plurality of through holes. Also disclosed is a method for humidifying dry air in a hybrid humidifier.

Abstract: 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.

Abstract: 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.

Abstract: A fuel cell stack humidification device includes: an air flow field provided on a fuel cell separator and including an inlet portion and an outlet portion; and a water absorbing member mounted on both sides and the bottom of the air flow field to transfer water in the outlet portion to the inlet portion. The humidification device can provide an auxiliary humidification function and minimize the volume that a humidifier occupies in a fuel cell vehicle.

Abstract: A humidification device for a fuel battery system, which rapidly exchanges dry air with humid air over a wide area, thus increasing humidification efficiency, and which appropriately heats dry air and humid air during cold weather, thus preventing the moisture of humid air from freezing, therefore being effectively used in cold regions. The humidification device includes a hollow fiber membrane to pass dry air and humid air so that moisture exchange is conducted between the dry air and the humid air, and a dry air guide pipe to supply new dry air into the hollow fiber membrane.
