Abstract

A membrane assembly for a humidification device of a fuel cell system may include a membrane. The membrane may be permeable to water and impermeable to air. The membrane may extend in a flat form in a longitudinal direction and in a transverse direction that is transverse with respect to the longitudinal direction in an extent plane. The membrane may include in a height direction extending transversely with respect to the longitudinal direction and transversely with respect to the transverse direction a top side and a bottom side averted from the top side. The membrane may include an encircling outer margin in the extent plane. The outer margin may have an upper edge at the top side and a lower edge at the bottom side, between which an encircling face surface extends.
