Abstract

The present invention relates to electrode membranes which comprise an ion-exchange material forming a core zone, with electrodes bonded thereto on both sides, the ion exchange material being formed from homopolymers soluble in solvents, or copolymers or mixtures thereof. The polymers must have at least one residue dissociable in ions. The electrode material is connected on either side of the core zone to the ion-exchange material to form an intimate contact between the electrode and the ion exchange materials, while the external sides of the electrode are pure electrode material. The electrode membranes are useful for forming fuel cells or electrolyzers.
