Periodic Reporting for period 1 - NEWBORN (NExt generation high poWer fuel cells for airBORNe applications)
Periodo di rendicontazione: 2023-01-01 al 2023-06-30
NEWBORN focuses on development and demonstration of the TRL 4 ground demonstrator of the overall propulsion system using fuel cells technology for electricity generation. The fuel cell power source technology will consist of 1MW modules, which can be paralleled to exceed the 3 MW power levels defined by the CAJU call. The consortium plans to market the technology early aboard the CS-23 19-pax commuter aircraft – 2 systems, total system take-off power of ~2 MW.
The key innovation areas of the project are:
* Internally modular aerospace PEM fuel cell stack with high power density of >5kW/kg, operating temperature >105 °C, and high output power (designed for up to 1 MW, demonstrated in an intermediate configuration of 720 kW)
* Self-regulated structural and conformal load-bearing cryogenic tank with high gravimetric index and minimal boil-off in 24 hours.
* Dual architecture air supply system
* Tightly integrated thermal management system
* Lightweight & low pressure drop heat exchangers
* Multi-fidelity digital twin
* Redundant modular bus-tie DC/DC converters with extreme power density of >20 kW/kg and >98% efficiency, scalable up to 10 MW
* High availability control system architecture
* Scalable high voltage propulsion subsystem with high power density
* Battery pack technology concept with innovative thermal management
