Abstract: A fuel cell stack includes a plurality of stacked fuel cell units and at least one stack end element that are clamped a clamping device. The clamped fuel cell units are surrounded by a housing. A circumferential seal, in particular a lip seal, which has recesses for accommodating the clamping device is situated between the housing and the at least one stack end element. The clamping device is electrically insulated at least in the area of the recesses.

Abstract: Package (1) for an implant (2), in particular for a dental implant, comprising a housing (5) with a compartment (51) that can be closed by way of a pivotable and/or slidable cover (4) so as to be essentially liquid-tight, said compartment being intended for a first section (2?) of the implant (2), and an area (19) for a second section (3) of the implant (2), said area being separated rated from the compartment (51) by way of a housing wall (8), wherein a passage (35) connecting the compartment (51) and said area (19) is provided in the housing wall (8) for a transition section (3?) between the first section (2?) and the second section (3) of the implant (2), and wherein the housing wall (8) comprises a removal slot (9, 36) for removal of the implant when the cover (4) is open without separating the sections (2, 3).

Abstract: The inventive end plate comprises pressure shield (21) and a supporting plate (30), whereby the forces, which serve to compress the stack (1) of fuel cells (2) and which are introduced via the force introduction locations (24), are introduced into the stack in the form of a compressive load in a defined and uniform manner.
