基于质子膜燃料电池(PEMFC)和热驱制冷,提出一种舱外航天服冷电联储方法,根据热力学总能理论,通过能量的梯级利用和不同形式的能量联产来实现舱外航天服生命保障系统冷电联储、能源转化和环境控制一体化。对舱外航天服生命保障冷电联储系统进行了热力学分析,表明本文舱外航天服生命保障系统冷电联储方案与传统方案相比,能达到减少航天员出舱活动携带物品种类和提高能源利用率的目的。并重点对冷电联储系统储氢冷却器相关参数的选取对系统一次能源利用率及系统整体质量的影响进行分析,结果表明LaNi5和LmNi4.9Sn0.1较适合用于本文提出的舱外航天服生命保障冷电联储系统。
Based on the proton membrane fuel cell (PEMFC) and heat-driven refrigeration, a cold-power storage tank-space suit is proposed. According to the theory of thermodynamic total energy, life in spacesuit spacesuit can be realized by cascade utilization of energy and different forms of energy cogeneration. Guarantee System Cold-Fed, Energy Conversion and Environmental Control Integration. Thermodynamics analysis of the cold-proof electricity storage system for life-space protection of spacesuitsuits shows that the cold-electricity storage system of the liferaft spacesuit life-support system in this paper can reduce the types of objects carried by the astronaut’s activities and improve the energy utilization compared with the traditional scheme Rate the purpose. The paper also analyzes the impact of selecting parameters related to the primary hydrogen storage system and the overall quality of the system. The results show that LaNi5 and LmNi4.9Sn0.1 are more suitable for the spaceborne space suit proposed in this paper Life Insurance Cold Electricity Federal Reserve System.
