Abstract
Life Systems, Inc. under the sponsorship of the National Aeronautics and Space Administration (NASA), has developed Electrochemical Carbon Dioxide (CO2) Concentration technology that removes CO2 continuously or cyclically from low CO2 partial pressure (400 Pa (3 mm Hg)) atmospheres with the performance and operating characteristics required for Space Station application. The most recent advancement of this technology is the development of an advanced preprototype subsystem, the CS-3A, to remove the metabolic CO2 produced by three persons from the projected Space Station atmosphere.
This paper provides an overview of EDC technology, shows how it is ideally suited for Space Station application and presents technology enhancements that will be demonstrated by the CS-3A subsystem development program.
