Abstract
Systems and methods for one or more bipolar plate and a stack for an electrochemical system. The bipolar plate comprising a first individual plate and a second individual plate. The first individual plate has at least one first positioning opening with a first crimping. The second individual plate has at least one second positioning opening with a second crimping. The first positioning opening and the second positioning opening of the individual plates arranged in alignment with each other. The first crimping forms at least one first contact area for a first positioning pin and the second crimping forms at least one second contact area for the first positioning pin.

A bipolar plate for an electrochemical system, comprising:
- a first individual plate and a second individual plate connected to each other,
- the first individual plate has at least one first positioning opening with a first crimping, the first positioning opening being at least partially surrounded by the first crimping,
- the second individual plate has at least one second positioning opening with a second crimping, wherein the second positioning opening is at least partially surrounded by the second crimping,
- the first positioning opening and the second positioning opening of the individual plates are arranged in alignment with each other and form a positioning opening of the bipolar plate,
- the first crimping forms at least one first contact area for a first positioning pin and the second crimping forms at least one second contact area for the first positioning pin.
A method for producing a bipolar plate, comprising:
- providing a first individual plate and a second individual plate;
- creating at least one first positioning hole in the first individual plate and at least one second positioning hole in the second individual plate;
- forming the first individual plate in such a way that a first edge of the first positioning hole is at least partially crimped to form a first positioning opening, so that the first positioning opening has a first crimping;
- forming the second individual plate in such a way that a second edge of the second positioning hole is at least partially crimped to form a second positioning opening, so that the second positioning opening has a second crimping;
- positioning the positioning openings of the individual plates on a first positioning pin, wherein the two crimping s of the individual plates come into contact with the first positioning pin, and
- joining the two individual plates.
