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 process for joining a battery element () by at least one polymer thread (), comprises the method steps:

Method for joining a battery element

A method for manufacturing a battery cell () and a battery cell () comprises providing a battery housing () and introducing electrodes () and an electrolyte () into the battery housing (). At least partial regions () of a surface, in particular an outer surface, of the battery housing () are coated with a diffusion barrier layer () made of a polymer material () and then the polymer material () of the diffusion barrier layer () is oxidized at least on the surface to form an oxide layer (). The polymer material () may be in particular silicone so that the oxide layer () consists of silicon dioxide. An oxide layer () thus generated increases a barrier effect of the diffusion barrier layer () considerably and may be generated using technically simple means, such as for example an atmospheric pressure plasma.

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.
