Abstract
A humidifier for humidifying a dry cathode supply air via a moist cathode exhaust air in a fuel cell system is disclosed. The humidifier may include a housing, a membrane stack, two opposing sealing plates, and a support frame. The membrane stack may be arranged in and insertable into the housing interior in a longitudinal direction. Two opposing side surfaces of the membrane stack may be hermetically sealed. Dry cathode supply air in a supply air flow path and moist cathode exhaust air in an exhaust air flow path may be flowable through the membrane stack free of mixing. The two sealing plates may each be connected to an associated side surface of the membrane stack and may contact the housing in a sealing manner such that two air chambers are separated in an airtight manner transversely to a circulation direction extending around the longitudinal direction.
