FUEL CELL SYSTEM

摘要

The invention relates to a fuel cell system, comprising a fuel cell stack (1), with a layering of several fuel cells (2), separated from each other by means of bipolar plates (3; 3'). Said bipolar plates have openings for cooling (4), or the medium supply (5a) or the medium emptying (5b) of the fuel cells. The fuel cell stack may be mechanically pressurised in the direction (6) of the layering. Elastic beading arrangements (7; 7') are at least partly provided, for sealing the openings (4, 5a, 5b, 10).
