    摘要： The invention relates to a bipolar plate (15) for a fuel cell stack (10), comprising a first sealing section (157) on the side (151) of the bipolar plate and a second sealing section (158) on the second side of the bipolar plate. The sealing sections are designed to interact with an elastic sealing element (16) in a sealing manner in a fuel cell stack (10). According to the invention, the first and the second sealing sections of the bipolar plate (15) are asymmetrical, in that at least one sealing protrusion (1571) is formed in the first sealing section (157) and the second sealing section (158) has no sealing protrusion and/or is substantially flat. If such bipolar plates (15) interact with flat sealing elements in alternation in a fuel cell stack (10), good sealing of the stack can be achieved with low required pressing forces.
