Document Type and Number:
WIPO Patent Application WO/2023/118492
Kind Code:
A3
Abstract:
It is described a high-pressure alkaline electrolyzer for splitting water into hydrogen and oxygen, said electrolyzer comprising a stack of electrolysis cells (1), with channels supplying lye to the cathodes and anodes and channels conducting hydrogen from the cathodes and oxygen from the anodes. The electrolyzer includes first and second lye inlet channels (4a, 4b), a multitude of first intermediate lye channels (5a) conducting lye from the first lye inlet channel (4a) to each cathode (3a) in the stack, a multitude of second intermediate lye channels (5b) conducting lye from the second lye inlet channel (4b) to each anode (3b) in the stack, wherein the hydrogen conducting channels include a common hydrogen outlet channel (7a) and a multitude of intermediate hydrogen channels (8a) conducting hydrogen from each cathode (3a) to the common hydrogen outlet channel (7a), and the oxygen conducting channels include a common oxygen outlet channel (7b) and a multitude of intermediate oxygen channels (8b) conducting oxygen from each anode (3b) to the common oxygen outlet channel (7b).
