Electrolyzer for alkaline hydrogen electrolysis

Abstract

An electrolyzer for alkaline hydrogen electrolysis, comprising a DC voltage source, in particular a rectifier (1) with an electrical positive pole (2) and an electrical negative pole (3), as well as media supply lines (4) for an electrolysis medium and media outlets (5) for product media, wherein several electrolysis blocks (6) connected in series via electrical connecting lines (9) are connected between the positive pole (2) and the negative pole (3), wherein the electrolysis blocks (6) each have a plurality of electrically connected in series and flush mechanically clamped electrolysis cells (7), wherein the media supply lines (4) and the media outlets (5) each run serially through the electrolysis blocks (6) and are distributed within each individual electrolysis block (6) to individual cell supply lines (4', 4'') and individual cell outlets (5', 5'') of the electrolysis cells (7).
