  • Patent number: 11926912
    Abstract: The invention is related to an electrode assembly for an electrochemical process comprising a current supply device, an elongated current distribution bar comprising first and second ends, and a sheet-shaped electrode substrate attached to the current distribution bar and having a longitudinal extension and a lateral extension. The current distribution bar comprises a first portion attached to the current supply device, a second portion extending along the electrode substrate, and a third portion extending between the first and second portions. The current distribution bar is bent between its first and second ends, and the current supply device is laterally and longitudinally positioned beyond the electrode substrate. The second portion at least partly extends longitudinally along the electrode substrate.

  • Publication number: 20130280625
    Abstract: A method of preparing a gas diffusion electrode comprising a diffusion layer, and a reaction layer arranged to each other, wherein the diffusion layer is prepared by i) admixing a) sacrificial material, b) polymer and c) a metal-based material and d) optional further components, wherein the sacrificial material has a release temperature below about 275° C. and is added in an amount from about 1 to about 25 wt % based on the total weight of components a)-d) admixed; ii) forming a diffusion layer from the admixture of step i); iii) heating the forming diffusion layer to a temperature lower than about 275° C. so as to release at least a part of said sacrificial material from the diffusion layer. A gas diffusion electrode comprising a diffusion layer and a reaction layer arranged to one another, wherein the diffusion layer has a porosity ranging from about 60 to about 95%, and an electrolytic cell comprising the electrode.
