| 摘要 |
The invention relates to a pressure electrolyser comprising a pressure reservoir (2) and an electrolysis cell block (3) which is arranged in the pressure reservoir and contains a number of electrolysis cells (4) forming a stack. Said electrolysis cells (4) respectively contain anodes (11) and cathodes (12), and a lye circulation system is provided for supplying an anolyte to the anodes (11) and for supplying a catholyte to the cathodes (12). The electrolysis cell block (3) comprises a housing (5) which creates a seal in relation to the inside of the pressure reservoir (2). According to the invention, the housing (5) of the electrolysis cell block (3) and the pressure reservoir (2) form at least two separated chambers (7, 8) which form part of the lye circulation system and are defined by the housing (5), in relation to the electrolysis cells (4), and by the pressure reservoir (2), in relation to the environment. In preferred embodiments, one of the separated chambers (7) forms part of an anolyte circulation system and the other separated chamber (8) forms part of a catholyte circulation system.
