Under the Space Station Freedom Program, Boeing is responsible for Work Package (WP) 01 which includes the Habitat and U.S. Laboratory modules. That responsibility includes the integration of the system components of the Environmental Control and Life Support System (ECLSS). Included in the ECLSS is the Air Revitalization Subsystem (ARS). The ARS provides for removal and reduction of metabolic carbon dioxide, removal of trace contaminants, continuous monitoring of the cabin atmosphere composition and oxygen generation. This paper will focus on the oxygen generation aspect of the Space Station Freedom (SSF) ARS. A Static Feed Water Electrolysis System (SFWES) has been selected by Boeing as the oxygen generator for SSF. The SFWES generates oxygen and hydrogen by the electrolysis of water. Onboard SSF, the feedwater to be electrolyzed will be obtained from the potable water processor.
