Abstract: A humidifier for humidifying dry cathode incoming air via humid cathode outgoing air for a fuel cell system may include a housing, two end plates, supporting elements, and a membrane stack including membranes arranged one after another in a stacking direction. The membrane stack may have two opposing first longitudinal faces, two opposing second longitudinal faces, and two opposing end faces. Fluid may be flowable through the first and second longitudinal faces and may not be flowable through the two end faces. The first and second longitudinal faces may be aligned parallel to the stacking direction. The two end faces may be aligned transversely to the stacking direction. The supporting elements may be configured to absorb forces acting along the stacking direction, arranged in pairs opposite each other on the first and/or second longitudinal faces, and/or attached to the two end plates.

Abstract: A membrane stacking unit for a humidifier for a vehicle powered by fuel cells is disclosed. The membrane stacking unit includes a cuboid membrane stack with a plurality of flexible membranes stacked in a stacking direction, with four side faces through which air can flow and two end faces through which air cannot flow. Two sealing frames are assigned to two opposing side faces of the membrane stack. The respective sealing frame has a circumferential sealing region and a circumferential region projecting vertically. The respective sealing frame has a recess that is filled with an adhesive for sealing to the membrane stack.

Abstract: A filter device for filtering a fluid may include a flat filter element. The flat filer element may extend flat in a longitudinal direction and a transverse direction. The filter element may include at least one pleated filter medium through which a flow path of the fluid leads in a height direction. The at least one filter medium may include a top side and a bottom side facing away from the top side. At least one strainer may be arranged on the top side. The at least one strainer may extend flat parallel to the filter medium and may include a strainer material having multiple passages such that the flow path leads through the strainer in the height direction.

Abstract: A battery module for a traction battery of a battery electric vehicle and a method for manufacturing a battery module are disclosed. The battery module includes a cohesive battery cell stack and a module housing. A guide unit with at least two guide rails are provided on two opposite sides of the battery module. The battery cell stack is inserted into the module housing in a direction of insertion via the at least two guide rails and held transversely to the direction of insertion. The battery cell stack is bonded to the module housing via a cured adhesive. The cured adhesive defines a form-fitting unit that holds the battery cell stack in the module housing in at least one of a form-fitting and force-fitting manner.

Abstract: A housing for an energy storage device of a vehicle may include a main housing and a temperature control plate. The main housing may form a housing interior for a plurality of energy storage cells of the energy storage device. A temperature control fluid may flow through the temperature control plate for the temperature control of the plurality of energy storage cells. The main housing and the temperature control plate may be configured such that the temperature control plate can be inserted into the housing interior in an insertion direction. In an inserted configuration, the temperature control plate may form a positive connection with the main housing which may prevent displacement of the temperature control plate in the main housing transversely to the insertion direction.

Abstract: A positioning device for location positioning of a plurality of energy storage cells of an energy storage device of a vehicle, a cover for closing such a positioning device, an energy storage device with such a positioning device, and a such cover are provided. The present disclosure is based on a general idea of providing a positioning device for energy storage cells which allows both material savings and functional integration of a number of functions.
