FUEL CELL, FUEL CELL STACK AND METHOD FOR SEALING A FUEL CELL

摘要

The invention relates to a fuel cell (1) with a membrane electrode assembly (2). The membrane electrode assembly (2) is disposed between two bipolar plates (5, 6) and connected to a sealing element (3). The sealing element (3) and the bipolar plates (5, 6) contact each other with the formation of an abutment region (10). A sliding surface (11) is provided in the abutment region (1), by means of which the membrane electrode assembly (2) disposed between the two bipolar plates (5, 6) can be impacted with a shear stress (15) upon compression of the two bipolar plates (5, 6). The invention further relates to a fuel cell stack with such a fuel cell (1) and to a method for sealing a fuel cell (1).
