Recently, the Tianzhou-5 fuel cell carrying load project undertaken by the 529 Factory of the Fifth Academy of China Aerospace Science and Technology Corporation successfully completed the on-orbit experiment task, marking my country's first completion of the space fuel cell 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. The follow-up fuel cell project team of Plant 529 will, on the basis of this verification work, carry out in-depth engineering research on the space fuel cell energy system to realize the aerospace application of my country's fuel cell energy system.
