Bipolar plate for fuel cells with three individual plates, fuel cell stack with such bipolar plates and vehicle with such a fuel cell stack

摘要

The invention has for its object to provide a bipolar plate (15), which has a mechanical robustness, but can still be configured flexibly. The bipolar plate (15) comprises an anode plate (50) having a first structure (52) for forming an anode flow field, a coolant plate (60) having a second structure (62) for forming a coolant flow field and a cathode plate (70) a third structuring (72) for forming a cathode flux field. In this case, the coolant plate (60) between the anode plate (50) and the cathode plate (70) is arranged. According to the invention, at least two of the first, second and third structurings (52, 62, 72) differ from one another. Furthermore, a fuel cell stack with bipolar plates (15) according to the invention is claimed and furthermore a vehicle with fuel cell stacks according to the invention.
