ABSTRACT:
The membrane serves to cover a gas diffusion electrode on its outside surface facing a liquid electrolyte. The membrane is impermeable to gas and water-absorbent. It comprises a textile carrier layer. At least one gas-sealing layer, which contains ion exchange material and binder in a weight ratio from 10:1 to 1:2, is bonded to the textile carrier layer. In the manufacture of the membrane, an adhesive layer consisting of a binder in a solvent and subsequently at least one gas-sealing layer are applied to the textile carrier layer.
