Abstract

The invention relates to a renewable fuel cell, which specifically comprises a plurality of fuel cell units and water electrolysis cell units, wherein the fuel cells and the water electrolysis cell units are overlapped together through water plates to form the renewable fuel cell with a fuel cell function and a water electrolysis tank function, the fuel cell has a non-attitude drainage capacity, and the water electrolysis tank has a non-attitude water supply capacity. The renewable fuel cell is small in size, long in service life and suitable for long-term operation in a microgravity environment.

Description

technical field [0001] The invention relates to the technical field of renewable fuel cells (RFC), and mainly relates to a combined structure of a proton exchange membrane fuel cell and a solid polymer electrolyte water electrolysis cell. Background technique [0002] With the high attention to space technology in the world, space power supply technology has developed rapidly. A highly safe and reliable space power supply system is an important factor to ensure the normal operation of space vehicles such as satellites. On the one hand, the power supply system is used to control the attitude of space vehicles such as satellites, and at the same time, it ensures the normal operation of instruments and equipment carried by space vehicles such as satellites and the communication with the ground. Improving the performance and cost performance of space power supplies is of great significance to increasing the payload and improving satellite performance and efficiency. [0003] R...
