The Static Feed Electrolyzer (SFE) is being developed by the National Aeronautics and Space Administration (NASA) through Life Systems, Inc. (Life Systems) as part of NASA's effort to mature water electrolysis technology for application in the Space Station Environmental Control/Life Support System (ECLSS), Propulsion and Reboost System, Extravehicular Activity (EVA) and Electric Power System (EPS). The water electrolysis process generates metabolic oxygen (O2) for the crew cabin, EVA backpacks and air lock, and provides reactants for carbon dioxide (CO2) removal, CO2 reduction, propulsion/reboost systems and fuel cell electric power generation. The use within all of these applications will make water electrolysis a fundamental utilitylike technology for the Space Station.
