Abstract
The invention discloses a pressure electrolyzer comprising a pressure vessel (2) and an electrolytic-cell block (3) arranged in the pressure vessel (2) and containing a plurality of electrolytic cells (4) combined in the form of a stack. The electrolytic cells (4) in each case contain anodes (11) and cathodes (12), and an electrolyte-circuit system is provided for supplying an anolyte to the anodes (11) and for supplying a catholyte to the cathodes (12), and wherein the electrolytic-cell block (3) comprises a housing (5) which is sealed relative to the interior of the pressure vessel (2). The invention provides that the housing (5) of the electrolytic-cell block (3), together with the pressure vessel (2), forms at least two chambers (7, 8) separated from each other, which constitute a part of the electrolyte-circuit system and which are defined relative to the electrolytic cells (4) by the housing (5) and relative to the atmosphere by the pressure vessel (2). In preferred embodiments, one of the chambers (7) which is separated from another chamber constitutes a part of an anolyte circuit, and another of the chambers (8) which is separated from said one chamber constitutes a part of…
