NExt generation high poWer fuel cells for airBORNe applications

新生儿侧重于现实和商业上可行的项目成果，远远超过Call主题的预期成果。这是唯一能带来真正影响的途径，远远超出了文书工作和测试平台。考虑到这一点，该项目采用了踏脚石原则，并打算在尽可能安全的情况下尽快将航空分级燃料电池推向市场。这将产生操作数据，以支持CS-25飞机的认证。它将进一步在保守的航空运输环境中提供至关重要的接受差距缓解。18个多学科合作伙伴，包括3个非传统航空航天合作伙伴和2个中小企业，将致力于28项关键使能技术。到2030年，它们将成熟和优化，以支持CS-23飞机的EIS，到2035年支持支线飞机的EIS。该项目的目标是到2026年实现50%的整体推进系统效率，以传动轴上的能量与氢气较低热值的比率计算。这一雄心壮志大大超过了HPA-02呼吁的预期结果。同样，到2025年底，该项目将展示可广泛扩展的燃料电池电源技术，功率密度为>1.2 kW/kg，堆叠功率密度为>5 kW/kg。该技术将适用于FL250和FL450的不同最大飞行高度，到2026年可扩展至~250kW，并可用于SMR飞行高度的二次电源。一种创新的低温油箱概念将被集成，CS-23飞机的重量指数为35%，支线飞机的重量指数可达50%。该项目还将解决高功率密度高压能量转换、推进系统和下一代微管热交换器，以及整个系统的精确数字孪生。总之，新生儿将开发一个技术演示器，为清洁航空第二阶段的飞行演示做准备。

NEWBORN focuses on realistic and commercially viable project outcomes significantly exceeding the Call topic Expected Outcomes. This is the only path to bring a real impact, well beyond paperwork and test rigs. With this in mind, the project applies the steppingstone principle and intends to bring aviation graded fuel cells into the market as soon as safely possible. This will generate operational data to support certification on CS-25 aircraft. It will further provide vital acceptance gap mitigation in the conservative air transport environment. The 18 multi-disciplinary partners, including 3 non-traditional aerospace partners and 2 SMEs, will work on 28 key enabling technologies. They will be matured and optimized to support an EIS of CS-23 aircraft by 2030 and regional aircraft by 2035. The ambition of the project is to achieve an overall propulsion system efficiency of 50% by 2026, calculated as a ratio of energy on the propeller shaft to the hydrogen lower heating value. This ambition greatly surpasses the expected outcome of the HPA-02 Call. Similarly, by the end of 2025, the project will demonstrate widely scalable fuel cell power source technology with a power density of >1.2 kW/kg and stack power density of >5 kW/kg. Technologies will be adaptable to different maximum flight altitudes of = FL250 and =FL450, and scalable down to ~250kW and reusable for secondary power in SMR flying altitudes by 2026. An innovative cryogenic tank concept will be integrated, demonstrating a gravimetric index of 35% for the CS-23 aircraft and scalable up to 50% for regional aircraft. The project will also address high power density high voltage energy conversion, propulsion systems, and the next generation microtube heat exchangers, along with an accurate digital twin of the overall system. All together, NEWBORN will develop a technology demonstrator prepared for flight demonstration in Clean Aviation Phase 2.
