A rechargeable battery assembly for a vehicle has a metal-air rechargeable battery and a filter device to condition inlet air supplied to the metal-air rechargeable battery such that the inlet air exhibits predetermined inlet air values. The filter device has one or more filter elements, one or more sensor devices that determine at least one inlet air parameter, and one or more valve devices. A control system is coupled to the sensor devices so as to receive sensor signals for the at least one inlet air parameter and is coupled to the valve devices. The control system adjusts, depending on the received sensor signals, the valve devices in order to control the predetermined inlet air value in that the inlet air is guided through the filter elements; is guided past the filter elements; or is guided to an air outlet for regenerating the filter elements.

Rechargeable battery assembly for a vehicle

A rechargeable battery assembly for a vehicle has a housing and at least one metal-air rechargeable battery arranged in the housing. A filter device is arranged in the housing and conditions the inlet air of the at least one metal-air rechargeable battery such that the inlet air exhibits a predetermined air humidity. A flow deflecting device is provided that deflects the inlet air in the housing such that the filter device can be regenerated by waste heat of the at least one metal-air rechargeable battery.

A filter module has hollow fibers which are combined into fiber bundles having end face pottings. The pottings of the fiber bundles are received into a common end disk.

A humidification device is provided with at least one stacked unit with water vapor-permeable membranes arranged parallel and spaced apart relative to each other. The membranes each have an edge area framed by frames. The frames are formed by a film composite of a lower film and an upper film, wherein the lower and upper films of the film composite clamp the edge area of one or more of the membranes therebetween. The lower and upper films of the film composite are fixedly connected to each other. Alternatively, the frames are formed by a thermoplastic yarn that is sewn into the edge area of one or more of the membranes, respectively, wherein the thermoplastic yarn is reshaped by heat and pressure.

Humidification device, in particular for a fuel cell

A hollow fiber module of a device for separating fluids has hollow fibers with walls that have partially permeable structures. The hollow fibers are positioned parallel to each other. At least one areal fluid-permeable spacer medium with a structure that is self-supporting an areal state of the at least one spacer medium is provided and arranged between the hollow fibers such that the at least one spacer medium surrounds at least partially circumferentially a first one of two neighboring hollow fibers at least on a side of the first hollow fiber that is facing the second one of the two neighboring hollow fibers.

A humidifier for a fuel cell has a stacked unit of several water-permeable membranes which are parallel to each other and are arranged spaced apart form each other. On the edges of the membranes, a sealant is applied which closes a flow space between neighboring membranes fluid-tightly and serves as a spacer.
