On the 25th November 2022 Hours Hong Kong SAR – Beijing time CNSA –China National Space Administrationthe Tiangong –China Space Station Crew of Shenzhou 14 crew …..China, People’s Republic of China successfully completed the first space fuel cell space on-orbit experiment] Recently, the Tianzhou-5 fuel cell carrying load project undertaken by the 529 Factory of the Fifth Academy of Aerospace Science and Technology Group successfully completed the on-orbit experiment task, marking the first time my country has completed the space fuel cell test. Battery on-orbit test.
In the early stage, Factory 529 organized a fuel cell team composed of three majors: electric energy transmission and control, fluid drive and transmission, and surface engineering technology to complete the product development and successfully ship it. The on-orbit experiment has passed the cyclical verification of multiple working conditions, successfully completed all the established tasks, and achieved a complete success. It has preliminarily verified the power generation characteristics and variable power response of the fuel cell energy system in orbital vacuum, low temperature and microgravity conditions. The law and the interface characteristics of electrochemical reactions provide important data and theoretical support for the development of space fuel cell energy systems and key technology research.
