An electrolyzer system and a method for operating the electrolyzer system

Abstract

The various embodiments of the present invention describe an electrolyzer and a method for the electrolysis of water. The system (100) comprises at least one electrolyzer stack (101) that produces a first gas-electrolyte mixture in a first compartment of the stack (101), and a second gas-electrolyte mixture in a second compartment of the stack (101). A first separator (103) receives the first gas-electrolyte mixture through a first outlet (107) and separates the electrolyte from the first gas. A second separator (104) receives the second gas-electrolyte mixture through a second outlet (108) and separates the electrolyte from the second gas. A first inlet (105c) introduces at least the first electrolyte into the stack (101), and a second inlet (106c) introduces at least the second electrolyte into the stack (101).A first suction line (105a) connects a first pump (109) to the first separator (103), and a first header line (105b) connects the first pump (109) to the first inlet (105c) of the assembly (101). A second suction line (106a) connects a second pump (110) to the second separator (104), and a second header line (106b) connects the second pump (110) to the second inlet (106c) of the assembly (101). An interconnecting line (111) connecting the first header line (105b) to the second suction line (106a) is configured to supply a portion of the first electrolyte, at a predetermined mixing rate, from the first header line (105b) to the second suction line (106a). The predetermined mixing rate is directly proportional to the electrical current applied to the assembly (101).
