Embodiment Construction
[0045] figure 1 An electrochemical system 1 according to the invention is shown comprising a stack 2 of identically designed separator plates stacked in z-direction 7 and clamped between two end plates 3,4. The separator plates are here formed as bipolar plates and each comprise two individual plates connected to each other. In this example, system 1 is a fuel cell stack. Each two adjacent bipolar plates of the stack 2 thus enclose between them an electrochemical cell designed to convert chemical energy into electrical energy. In alternative embodiments, the system 1 can also be formed as an electrolyzer, an electrochemical compressor or a humidifier for a fuel cell system. Separator plates are also used in those electrochemical systems. The structure of these separator plates corresponds to the structure of the bipolar plates explained in more detail here, even if the medium guided on or through the separator plates is different.

The invention relates to a separator plate (10) for an electrochemical system (1) comprising: at least one passage opening (10a-h) for forming media channels for feeding or discharging media; at least one bead arrangement ( 14a-h), which is arranged around the at least one passage opening (10a-h) for the purpose of sealing said passage opening (10a-h), wherein the side faces (21, 22) of the bead arrangement (14a-h) At least one of them comprises at least one opening (25, 26) for guiding the medium through the bead sides (21, 22); and at least one guiding channel (27) on the outside of the bead arrangement (14a-h) Connected to and fluidly connected to the bead interior (24) via openings (25, 26) in the bead sides (21, 22). The separator plate (10) is characterized in that the guide channel (27) is designed such that the guide channel (27) width (31) determined parallel to the flat surface plane of the separator plate (10) is arranged along said bead (14a-h ) direction increases at least in some parts.
Description
technical field [0001] The present invention relates to separator plates for electrochemical systems. For example, the electrochemical system may be a fuel cell system, an electrochemical compressor, a humidifier for a fuel cell system, or an electrolyzer. Background technique [0002] Known electrochemical systems generally comprise a plurality of separator plates arranged in a stack such that every two adjacent separator plates enclose an electrochemical cell or humidifier cell. The separator plates typically each consist of two separate plates connected to each other along the rear side away from the electrochemical or humidifier cells. For example, separator plates may be used to make electrical contact with electrodes of individual electrochemical cells (e.g., fuel cells) and / or to electrically connect adjacent cells (series connection of cells). The separator plates can also be used to dissipate the heat generated in the cell between the separator plates. Such waste...
