Operational humidifier for humidifying e.g. molecular hydrogen for fuel cells in fuel cell system for electricity generation, has duct provided at edge of seam arrangement for transmission of gas from port apertures to line structures

摘要

The humidifier (100) has inputs (A, B) supplying dry and moisten gases, and outputs (C, D) delivering moistened and dehumidified gases. Flow plates (2, 3) include gas line structures, and port apertures include median apertures for supplying and discharging gas with an elastic seam arrangement that is arranged around the port apertures. The median apertures are branched from the port apertures, and a duct e.g. circular duct, is provided at an edge of the seam arrangement for transmission of the gas from the port apertures to the gas line structures. The humidifier includes water transfer media that are executed as non-strengthened membrane selected from membrane laminate Gore-Tex (RTM: Waterproof/breathable fabric), ion-soaked membrane, ionomer membrane i.e. Nafion (RTM: Sulfonated tetrafluoroethylene based fluoropolymer-copolymer) or coated and/or impregnated fabric Texapore (RTM: Breathable and waterproof material) or Venturi (RTM: Not defined). The gas line structures are selected from fabric, knitted fabric, blooming mill stand, slats, nub films, shaft or stamping structures from plastic deformable materials. The flow plates are partially made by corrosion-stable metallic materials e.g. metal sheets and/or films, that partially consist of thermoplastic, elastomer or duro plastic plastics. The gas line structures are equipped as gas line channels. An independent claim is also included for a fuel cell system.
