Objective To carry out adaptability design of oxygen generation assembly by electrolysis( OGA) for microgravity and variable pressure environment condition in spacecraft. Methods Microgravity adaptability design of electrolysis cell stack was accomplished by simulation method on two-phase flow and an OGA system flow suitable for microgravity and variable pressure environment was designed. Testing device for evaluating the design rationality was developed. Results The OGA worked stably in TG-1 space module. It produced2097. 8 SL oxygen during 96. 88 h,and the yield reached 0. 74 kg / d. Conclusions Design scheme of the OGA meets the requirements of space environment,and the ground-based evaluation methods are feasible.
