AbstractFor future long-term manned space missions and moon bases, it is required to provide not only energy storage and power generation but also life support system and propulsion for attitude and orbit control. We have proposed and studied the Water-Energy-Cycle Space System, which consists of a solar panel, a water electrolysis system, a fuel cell, and a propulsion system. Therefore, this system can support long-term and large-scale space activity. During eclipse periods etc, the hydrogen and oxygen which were stored are used for power generation by fuel cells, or are used as propellant of a spacecraft. In addition, it is highly efficient and non-toxic to humans to use hydrogen/oxygen as propellants. We have previously made a proof model of the Water-Energy-Cycle Space System when it will be assumed to install International Space Station (ISS) module "JEM", and executed the system performance examinations. As the results, the fundamental knowledge was sufficiently obtained. However, aiming to further establishment of the appropriate system and each component for demonstration experiments in orbit, it is essential to overcome the following technical issues in terms of the power generation and energy storage; development of the fuel cell for space uses diverted from ground-based technology; and basic study on the water electrolysis system and its application into actual utilization. So, we carried out trial manufacture and basic characteristic measurement for a fuel cell and an electrolysis cell with modification for the Water-Energy-Cycle Space System. The purpose of our work is to establish the component technology by means of examination and evaluation on these experimental cells. Current-voltage characteristics on the both cells were measured to understand their basic performance. As to the electrolysis cell, validation between electrolysis current and quantity of generated gas and pressurized test of hydrogen/oxygen for energy storage were also conducted. This paper reports the evaluation results of the basic performance and the operation tests for the electrolysis cell. Additionally, we have made a system study on the application of the Water-Energy-Cycle Space System.
