Abstract: The device serves for mechanically applying to the surface of a work piece a flexible multi-layer body member which is adherent on it one side and is composed of a supporting layer, an adhesive layer and a draw-off protection foil covering said adhesive layer.Said device comprises the following partial devices:(a) a supporting table for supporting said multi-layer body member;(b) separating device for separating said protection foil from said multi-layer body member in a marginal zone;(c) a draw-off device for drawing off said protection foil from said multi-layer body member; and(d) a transporter provided with a vacuum gripper for lifting said multi-layer body member off from said supporting table, for moving it past said draw-off device, and for deposing it--if necessary after heating it by means of a heating device--onto the surface of said work piece.

Abstract: Especially for bipolar membrane electrolysis cells, cathodic current collectors (8) are required which have a high electrical conductivity, a large contact surface area and a sufficient porosity to ensure the passage of reaction educts and products, for example, water and gas. At the same time, they should be chemically, mechanically and thermally stable. No protective voltage should be required while the cells are closed down. The current collector consists of graphite powder (12) of high purity, having particle sizes in the range from 10 .mu.m-200 .mu.m, and carbon fibres (13) which are irregularly distributed therein and have lengths from 1 mm to 30 mm, the graphite powder/carbon fibre mass ratio being in the range from 10:1 to 30:1. The binder used is polyvinylidene fluoride. For producing the current collector, the binder is dissolved in, for example, dimethylformamide.
