The fuel cell unit (114) includes a section (120) guiding liquid flow. This is bonded to the contact plate (118), liquid-tight. In addition it forms a boundary for the chamber through which fluid flows during fuel cell operation. It is formed from sheet. A...

The flat seal has a seal plate of a metal plate layer (26) and a sealing element (50). The element is formed from a material, applied to a main surface of the metal layer and hardened in situ. In this area, the layer has an aperture (56) for the passage of...

The flat seal has a seal plate of two metal plate layers (22,24,26), and sealing element (50), which consists of a material applied to a first metal layer (26) and hardened in situ. The material is initially plastically deformable when machine components a...

The seal has a long seal plate and a seal plate end strip. The outer edge of a central edge strip section (100) is bent out of the plate level in a direction opposite to the direction, in which the strip is curved during fitting of the seal. The outer edge...

The seal consists of two cover plates (1) and an element (2) between them. The element has a spring travel limiter (9) for the beads (4) around the apertures (3) in the plates. It also has one or more plastically deformable sealing layers (10) in at least ...
