Fuel cell unit in the form of a fuel cell stack for producing electrical energy in an electrochemical manner, comprising fuel cells, the fuel cells each comprising a proton exchange membrane, an anode, a cathode, a gas diffusion layer, a bipolar plate, at least one fluid channel for the passage of a fluid, at least one seal () composed of a sealing material () for sealing off the at least one fluid channel (), wherein particles () composed of a particle material () are arranged in the sealing material () of the at least one seal (), for the purpose of extending the diffusion path () of the fluid which is sealed off by the at least one seal ().

Fuel cell unit

A method for forming a connection between a first battery cell () and a second battery cell (), wherein, in a first method step, an adhesive () comprising at least one first component () and at least one second component () is applied to the first battery cell (), wherein a first proportion () of the at least one first component () and/or a second proportion () of the at least one second component () is changed during the application of the adhesive () over the first battery cell (), wherein, in a second method step, the first battery cell () is connected to the second battery cell () in such a way that an inhomogeneous material bond is formed between the first battery cells () and the second battery cell ().

Method for forming a connection between battery cells, and battery module

A method for forming a thermally conductive connection between a plurality of battery cells () and a temperature-regulating body () of a battery module (), wherein, in a first method step, an adhesive () comprising at least one first component () and at least one second component () is applied to the temperature-regulating body () or to the plurality of battery cells (), wherein a first proportion () of the at least one first component () and/or a second proportion () of the at least one second component () is changed during the application of the adhesive () over the temperature-regulating body () or the plurality of battery cells (), wherein, in a second method step, the plurality of battery cells () is connected to the temperature-regulating body () in such a way that an inhomogeneous material bond is formed between the plurality of battery cells () and the temperature-regulating body ().

A cell housing plate for the arrangement of round cells, comprising a cover plate arranged on the top side of the cell housing plate, and a base plate arranged opposite the cover plate on the underside of the cell housing plate, wherein the cover plate and the base plate have a plurality of cut-outs arranged opposite each other for receiving the round cells, wherein the cut-outs each have a collar pointing radially towards the inside of the cut-out for receiving a sealant, and an opening arranged inside the collar for passage of the round cells, wherein the cover plate and the base plate are arranged relative to each other such that the cut-outs of the cover plate and the opposite cut-outs of the base plate form cavities for receiving sealant for sealing the round cells which may be arranged inside the cell housing plate.

Cell housing plate for the arrangement of round cells

An electrochemical cell includes a prismatic cell housing including a lid plate that closes one end of the housing. The cell also includes a terminal assembly having a simple structure that is supported on the lid plate. The terminal assembly includes the lid plate, a terminal and an adhesive layer that is disposed between and secures the terminal to the lid plate. The terminal assembly includes features that allow the adhesive layer to flow in a controlled and reproducible manner over the entirety of a predetermined area without flowing beyond the predetermined area. The features result from forming a stop line in the predetermined area by applying a surface treatment to the predetermined area. The stop line delineates a desired adhesive later outer boundary and engages the adhesive so as to maintain the adhesive within the predetermined area.
