Resumen de: WO2025131626A1

The invention relates to an electrolysis assembly (10) comprising a stack assembly (16). The stack assembly (16) is equipped with precisely one reactant gas manifold structure (66) in order to provide reactant gas to the electrolysis cells (18) and precisely one product gas manifold structure (68) in order to discharge product gas from the electrolysis cells (18). The stack assembly (16) has a reactant gas opening for introducing reactant gas into the reactant gas manifold structure (66) and a product gas opening for discharging product gas out of the product gas manifold structure (68). The reactant gas manifold structure (66) and the product gas manifold structure (68) are formed within the stack assembly (16), in each case by means of manifold openings introduced into the interconnectors, wherein between the membrane electrode assembly and the interconnector of at least some of the electrolysis cells is a reactant gas line structure designed to conduct reactant gas out of the reactant gas manifold structure along the hydrogen side of the membrane electrode assemblies and to the product gas manifold structure, and at least some of the membrane electrode assemblies have an oxygen-permeable structure on the oxygen side, said oxygen-permeable structure being positioned and designed such that oxygen released on the oxygen side of the membrane electrode assembly can be discharged into the interior of the housing (12).
