Zusammenfassung:A method of operating a solid oxide electrolyzer system includes providing a water inlet stream to at least one solid oxide electrolyzer cell (SOEC), generating a wet hydrogen product stream from the at least one SOEC, providing the wet hydrogen product stream to at least one hydrogen pump, generating a compressed hydrogen product and an unpumped effluent in the at least one hydrogen pump, and recycling at least a portion of the unpumped effluent upstream of the at least one hydrogen pump.
