Abstract：Oxygen generation technologies with lower requirement and higher performance urgently need to be developed to meet the challenges of manned lunar landing and Mars exploration.In this paper,the mission requirements,technical characteristics,key technologies and operation status of oxygen generation assembly by water electrolysis(OGAWE)in China Space Station(CSS)are introduced.Furthermore,the latest developments about oxygen generation by electrolyzing carbon dioxide based on solid oxide electroyte is reported.The application effects and research achievements demonstrate the oxygen generation by electrolysis is one of the most suitable techniques for oxygen regeneration in manned space mission.In addition,the oxygen generation by novel electrolysis technology provides feasible approach for improving the performance of oxygen regeneration and producing oxygen by in-situ utilization of extraterrestrial resource.These development experiments of OGAWE in CSS and research results of novel electrolysis provide valuable references for the technical progress of oxygen generation by electrolysis for manned spaceflight.
