Regenerative Fuel Cell System for Outer Space

外太空再生燃料电池系统

Honda is leveraging decades of hydrogen fuel cell technology expertise to develop a regenerative fuel cell system, known as a

本田正在利用其在氢燃料电池技术领域数十年的专业知识，开发一种再生燃料电池系统，称为

circulative renewable energy system

循环可再生能源系统

, that will continuously produce oxygen, hydrogen, and electricity. Honda envisions the circulative renewable energy system to be part of the infrastructure for humanity's sustained habitation on the Moon – utilizing the available resources of sunlight and water. By enhancing the performance of the circulative renewable energy system, improvements can be made to long-life regenerative fuel cells that can be used as a scalable, clean, and renewable energy source both in space and on Earth.   .

，该系统将不断产生氧气、氢气和电力。本田设想这种循环可再生能源系统将成为人类在月球持续居住的基础设施的一部分——利用可用的阳光和水资源。通过提升循环可再生能源系统的性能，可以改进长寿命再生燃料电池，这种电池可作为可扩展的、清洁且可再生的能源，应用于太空和地球。

During the Lunar Day, the system will use electricity generated by the sun to power the process. Honda’s high-differential pressure water electrolysis system will then produce hydrogen and oxygen from water.

在月昼期间，系统将使用太阳能产生的电力来驱动这一过程。本田的高差压水电解系统随后会从水中生成氢气和氧气。

During the Lunar Night, when the Moon is not receiving sunlight, some of the oxygen will be used for astronauts to breathe. The Honda fuel cell system will use the remaining oxygen, along with the hydrogen produced during the Lunar Day, to generate electricity.

在没有阳光照射的月夜期间，部分氧气将用于宇航员呼吸。本田燃料电池系统则会利用剩余的氧气和月昼期间产生的氢气来发电。

After the fuel cells generate electricity, the only byproduct is water, which is recycled back into the water electrolysis system to create a closed-loop energy cycle. This process is similar to how a home solar system operates on Earth, where daytime solar electricity is harnessed, and excess energy is stored in home energy batteries to provide power throughout the night..

燃料电池发电后，唯一的副产品是水，这些水会被回收到水电解系统中，从而形成一个闭环的能量循环。这个过程类似于地球上的家用太阳能系统的工作方式，白天的太阳能电力被捕获，多余的能源储存在家庭能源电池中，为整个夜晚提供电力。

International Space Station Testing

国际空间站测试

Honda has developed an advanced water electrolysis system designed to support long-term operations on the Moon by prioritizing efficiency and reliability. The system’s lightweight and compact design addresses the critical need to reduce transportation costs in lunar development. Additionally, since it doesn’t use mechanical compression, maintenance needs are reduced, enhancing reliability for extended missions.

本田开发了一种先进的水电解系统，旨在通过优先考虑效率和可靠性来支持月球上的长期运行。该系统的轻量化和紧凑设计解决了降低月球开发运输成本的关键需求。此外，由于它不使用机械压缩，维护需求减少，从而提高了长期任务的可靠性。

By enabling high-pressure gas storage in smaller containers, the system also reduces the need to transport and manage large numbers of tanks..

通过在较小的容器中实现高压气体存储，该系统还减少了运输和管理大量储罐的需求。

Honda will test the core part of its high-differential pressure water electrolysis system to verify the efficiency and reliability of the system in the microgravity environment of the ISS. For the ISS testing, Honda is collaborating with Sierra Space, a leading commercial space company at the forefront of innovation and the commercialization of space, and Tec-Masters, a leading provider of innovative scientific and technological solutions.

本田将在国际空间站的微重力环境下，测试其高差压水电解系统的核心部分，以验证该系统的效率和可靠性。在国际空间站的测试中，本田正与处于创新和太空商业化前沿的领先商业航天公司塞拉太空（Sierra Space），以及领先的创新科技解决方案提供商特克大师（Tec-Masters）合作。

Sierra Space will be the primary space mission integrator, working with NASA to transport materials on Sierra Space’s Dream Chaser® spaceplane, the world’s only commercial spaceplane. Tec-Masters will be the ISS technology expert..

塞拉空间公司将作为主要的太空任务集成商，与NASA合作，利用其全球唯一的商业太空飞机——塞拉空间公司的追梦者®太空飞机运送物资。Tec-Masters公司将担任国际空间站的技术专家。
