MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202617075174 A) filed by John Cockerill Hydrogen Belgium; and John Cockerill Hydrogen France on June 17, 2026, for Electrode Unit Produced By Resistance Welding, Electrolytic Cell And Electrolyser Comprising Same, And Corresponding Manufacturing Method.
Inventors include Saint-Arroman, Axel; and Chardome, Ingrid.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: The present application relates to an electrode unit (1216a, 1216b) for an electrolytic cell, comprising a planar electrode (12a, 12b) and an interlayer (16a, 16b) which is elastically deformable in a direction normal to the planar electrode (12a, 12b) and which has a thickness greater than a thickness of the electrode (12a, 12b) at least in a central region of the interlayer (16a, 16b), the interlayer (16a, 16b) comprising periphery regions crushed in said direction and connected to a periphery of the electrode (12a, 12b) by a weld made by resistance autogenous welding. An electrolytic cell and an electrolyser stack comprising such electrode units (1216a, 1216b) and a method for manufacturing such a stack are also described.
