Abstract

Solid Oxide Electrolysis is a technology that can generate oxygen from water vapor and carbon dioxide. Embedding Sabatier reactors allows for reclaiming oxygen from carbon monoxide produced by electrolysis as well as producing methane for fuel. Nafion is a technology that can passively pull water from a cabin atmosphere to be combined with CO2 and feed the electrolysis reactor. As little as 30% of water vapor contained in the cabin air may be required to supply 100% of oxygen supplies to crew. This paper describes an air revitalization system that uses solid oxide electrolysis, Sabatier reactors and Nafion to regenerate oxygen and produce fuel. Analyses will be presented to explore oxygen recovery, water recovery, system size and system power.
