regenerative

A fuel cell that converts the battery reaction product (water) into a reactant (hydrogen and oxygen) through an electrolyzer and then re-uses it to produce electrical energy is composed of two parts: a fuel cell and an electrolyzer. It can be used as an energy storage device for the power supply system of high power solar cell array. When there is sunlight, the solar array provides power to the spacecraft load, and is also used to decompose water into hydrogen and oxygen, so that some of the electricity is stored. When the spacecraft enters the shadow area, the solar cells cannot produce electricity or the power supply is insufficient. Hydrogen and oxygen fuel cells are devices that do not require all reducing agents and oxidants to be stored in the battery.

Static drainage

On June 13, 2014, China Aerospace Academy 811 Institute developed a static drainage fuel cell module, which successfully achieved long-term stable discharge of high current density, and achieved no gas emissions for 8 hours for the first time in China
