HIGH-TEMPERATURE ELECTROLYSER ARCHITECTURE, HAVING HIGH TARGET PRODUCTION BY AN ELECTROLYSIS CELL AND A LIMITED CELL DEGRADATION RATE

摘要

The invention relates to a device for high-temperature water electrolysis including: at least one basic electrolysis cell made of a cathode (2), an anode (4), and an electrolyte (6), inserted between the cathode and the anode, a first device (8.0) forming an electric and fluid interconnector consisting of a metal part delimited by at least one plane P1, said metal part including therein: a chamber and a plurality of holes (800, 8000, 8001) distributed over the surface, substantially perpendicular to the plane, and opening both onto said plane and into the chamber, the plane P1 of the first interconnector being in close mechanical contact with the plane of the cathode (2). The invention makes it possible to achieve a uniform current density in each electrolysis cell and to increase the rate of steam use by each electrolysis cell.
