Solid Oxide Electrolysis for Oxygen Production in an ARS

Oxygen regenerated from a crew's expired CO2 and H2O vapor is essential to enabling a continuous human presence on the moon at significantly reduced costs and risks. Any such technology demonstrated on the moon will then be ready to support the transport of humans to Mars and their eventual surface exploration efforts. Paragon Space Development Corporation is proposing an innovative, efficient and practical concept that utilizes Solid Oxide Electrolysis (SOE) for the next generation electrolysis/Sabatier subsystem to enable 100% oxygen regenerative air revitalization systems (ARS). The concept is innovative because it safely eliminates handling of hydrogen, works irrespective of gravity and pressure environments with no moving parts and no multi-phase flows, and requires no expendables while being compact with minimal impact on mass. This innovation is directly relevant and essential to our current mandate set by the President to return humans to the moon and in doing so develop technologies that will enable our exploration of Mars. The significance of the proposed Phase 2 SOE development effort is that it offers the very real possibility that life support systems could close the oxygen loop such that oxygen supporting consumables required to produce oxygen need not continually be delivered from Earth.
