HUMIDIFICATION CELL

摘要

The invention relates to a humidification cell (1) of a fuel cell assembly (41), comprising a water-permeable membrane (5) located between two external plates (9) of said humidification cell (1). One section of the surface of the membrane (5) is fitted to at least one of the external plates (9) and is thus partially covered by the external plate (9). This reduces the humidification capability of the membrane (5). To solve this problem, the inventive humidification cell (1) has a water-permeable supporting element (7a, 7b), which is located between the membrane (5) and one of the external plates (9).
