Methods for operating an electrolysis system that includes an electrolyzer for generating hydrogen and oxygen as product gases, a product gas flow being formed in a phase mixture including water and a respective product gas with a content of a foreign gas are provided. A rotation is impressed upon at least one product gas flow such that a phase separation of water and product gas is produced in the phase mixture, wherein the product gas is supplied to a catalytically active zone such that foreign gas is recombined with the product gas in order to form water, and after flowing through the catalytically active zone, the product gas released from the foreign gas is mixed with the liquid phase again in order to form a phase mixture.
A method for operating an electrolysis system comprising an electrolyzer for producing hydrogen (H2) and oxygen (O2) as product gases, with formation of a product gas stream in a phase mixture comprising water (H2O) and a respective product gas with a proportion of a foreign gas, characterized in that rotation is imparted to at least one product gas stream so as to bring about phase separation of water (H2O) and product gas in the phase mixture, wherein the product gas is supplied to a catalytically active zone in which foreign gas is recombined with the product gas to form water (H2O), and wherein, after passage through the catalytically active zone, the product gas, from which the foreign gas has been removed, and a liquid phase are remixed to form a phase mixture.
A recombiner for cleaning a product gas stream from water electrolysis, comprising an inflow region with an inlet and comprising a catalytically active zone which is arranged downstream of the inflow region based on an axial flow direction (Z) and which is adjoined by an outflow region with an outlet, thus forming a flow channel, wherein a swirl element is arranged in the inflow region and the catalytically active zone comprises a catalyst designed for axially central flow of the product gas through the flow channel, and wherein the outflow region is designed for remixing of phases, thus making it possible to obtain a cleaned product gas stream.
