Abstract

The Japan Aerospace Exploration Agency (JAXA) has been developing closed Environmental Control and Life Support System (ECLSS). Air revitalization system in closed ECLSS consists of five subsystems, CO2 removal assembly, Trace contaminant control assembly, CO2 reduction assembly, O2 generation assembly, and methane decomposing assembly. In this paper, development status of each subsystem exclude trace contaminant control assembly is reported. In CO2 removal system development, CO2 for almost 4 crews collected by low and narrow range of temperature swing of newly developed adsorbent. Full-scale test model of CO2 reduction system, loaded low temperature catalyst JAXA developed, has been completed. Prolonged test of electrolysis cell is in progress for examination O2 generation system architecture. Fundamental data for scale-up test of methane decomposition was conducted.
