In the process of exploring the universe, energy system is very important. Solar power generation is limited, and a variety of energy systems need to be developed. Recently, China completed the first space fuel cell experiment in orbit, proving the possibility of fuel cell cycle power generation in space.

The Tianzhou 5 fuel cell payload project, undertaken by the 529 Plant of the Fifth Academy of China Aerospace Science and Technology Corp, has successfully completed its in-orbit test mission, marking the country's first in-orbit test of a space fuel cell, according to reports.

In the early stage, the 529 plant organized a fuel cell team composed of three majors, namely electric energy transmission and control, fluid drive and transmission, and surface engineering technology, to complete the product development and smooth shipment.

During the in-orbit experiment, all the tasks have been completed successfully through the cyclic verification of several operating conditions.

The power generation characteristics, variable power response law and interface characteristics of electrochemical reaction of the fuel cell energy system under vacuum, low temperature and microgravity conditions in orbit were preliminarily verified, which provided important data and theoretical support for the development of space fuel cell energy system and key technology research.

The 529 plant fuel cell project team will further carry out engineering research of space fuel cell energy system on the basis of this onboard verification work, and realize the aerospace application of Chinese fuel cell energy system.

On November 12, a Long March-7 Yao-6 carrier rocket successfully launched the Tianzhou V cargo spacecraft,The mission sent about five tons of supplies to China's Tiangong space station, including a fuel cell power system.

According to Wan Cheng 'an, chief engineer of the 529 Plant's power transmission and control technology, the traditional photovoltaic power generation system cannot meet the spacecraft's energy needs.Space fuel cells generate electricity through an electrochemical reaction to produce water, which is then electrolyzed to produce hydrogen and oxygen to form a renewable energy system.

It can also be integrated with spacecraft propulsion, thermal control, environmental control and other sub-systems. It is an efficient, clean and in line with the future development of spacecraft new energy.
