Abstract: An anchoring unit for a system, the anchoring unit having at least one first insulation layer and at least one second insulation layer. The anchoring unit furthermore includes a support layer for mechanically stabilising the insulation layers, the support layer being arranged between the first insulation layer and second insulation layer. The anchoring unit furthermore includes at least two screws, the screws being oriented in opposition to one another, a first screw being suitable for anchoring to the system and a second screw being suitable for anchoring to an anchor object. A first screw head of the first screw is in direct contact with the support layer. A screw shank of the first screw is arranged at least partially in the first insulation layer. A method includes fastening a system to the anchoring unit.

Abstract: An electrolysis cell with a cell frame and to a method for producing an electrolysis cell, wherein the cell frame has a stepped inner profile. The inner profile has at least one support surface for receiving a planar component in the cell frame, and the support surface has a recess for a seal. A seal is first placed in the recess, and a membrane-electrode unit, a first gas diffusion layer, and an electrically conductive top layer are then introduced into the cell frame. The cell frame is then rotated, and a second gas diffusion layer is applied. The electrolysis cell produced in this manner includes the cell frame with the seal and the different layers.
