Humidification arrangement for moistening fuel cell stack of vehicle, has set of flaps arranged in one position in which humidification medium of humidification membrane flows in one direction that is different from another direction

摘要

The arrangement (10) has a humidification membrane (16), and an intake channel (22) that is arranged for intake of a supply air (12). A humidification medium i.e. exhaust air (20), is introducible into the humidification membrane through the intake channel. A discharge passage (24) is arranged for removing the humidification medium from the humidification membrane. A set of flaps (30, 32) is arranged in one position in which the humidification medium of the humidification membrane flows in one direction that is different from another direction. An independent claim is also included for a method for moistening a fuel cell stack.
