“…After the humidity of cabin air is reduced by a membrane dryer, the dried air is introduced into an absorption canister 4,5 in which CO 2 is absorbed by zeolite and concentrated by a temperature gradient. It is necessary to calculate the amount of zeolite required per person per day, and we assume the removal of 4,000 ppm → 0 ppm of CO 2 as the most demanding case.…”

To further advance manned space exploration, a critical issue that must be addressed is recycling of resources, especially air revitalization and water reclamation. Japan is already a leader in terrestrial environmental technologies, and aims to apply this know-how to develop air and water recycling technologies for space applications. To support proposed post- ISS missions such as manned lunar or asteroid exploration and an Earth-Moon Lagrange point (EML1) space station, JAXA is developing an air revitalization system for an on-orbit demonstration on the International Space Station (ISS) early in the extended ISS operation period (2015-2020). The requirements for this technical demonstrator have been investigated and its specifications established. Regenerative life support functions include oxygen recovery from carbon dioxide using a combination of CO 2 reduction by a Sabatier process and O 2 generation by electrolysis. Each air and water re-vitalization subsystem is planned to be transported to the ISS separately by successive H-II Transfer Vehicle (HTV)launches in the sequence Water Reclamation → Water Electrolysis → CO 2 Reduction. This paper presents the air re-vitalization system developed by JAXA, and gives details of water electrolysis in microgravity.
