Solar energy is available in daytime mission on the moon, but other energy sources are required at night mission, where day and night are repeated every 30 days. A regenerative fuel cell system is selected as the energy source of lunar mission. In the regenerative fuel cell system, hydrogen and oxygen gas are generated by excess power at daytime using electrical decomposition of water. On the other hand hydrogen and oxygen gas are transformed to water by fuel cell, and then electrical power is generated. In this paper, configuration and feasibility of regenerative fuel cell system for energy source of lunar mission is studied. The feasibility is also confirmed by basic experiment.
