摘要

An intermediate or end element for a fuel cell comprises a pressure distributor for evenly distributing pressure. An independent claim is also included for a fuel stack composed of stacked fuel cell units (11) and cooling plates (12). Preferred features: The pressure distributor comprises a pressure plate (2), a hollow chamber (3) and a piston (4). The hollow chamber is filled with an noncompressible pressure medium (30), preferably water, oil, silicone and/or other synthetic or natural medium.
