| 摘要 |
The invention relates to a humidification device (50) for humidifying process gases, in particular for fuel cells (12), comprising a stack (52) of repeating components, comprising a) a steam-permeable membrane (54), b) a first layer arrangement (56) arranged on a first side of the membrane (54), comprising b1) a first flow layer (60) for conducting a process gas to be humidified, comprising a multiplicity of flow channels (64) running parallel to the membrane (54), c) a second layer arrangement (58) arranged on a second side of the membrane (54), comprising c1) a second flow layer (66) for conducting a humidified gas, comprising a multiplicity of flow channels (64) running parallel to the membrane (54), and c2) two protective films (74) which adjoin the second flow layer (66) on both sides and have a multiplicity of through-openings (76). |
