The goal of the project is to develop high performance turbocharger for aeronautical application. This machine will allow increasing power density, efficiency and maintainability of the aeronautical piston engine. Key objectives for the equipment are: • High compressor pressure ratio (up to approx. 5:1) • High corrected compressor air flow rate (up to 350 g/sec) • Capability to be used in broad range of altitude (min. 6000m) and temperatures (ISA +/- 35°C) • Capability to cope with high gyroscopic loads (up to 9G and 4 rad/sec in all directions) • Long endurance at high loads (MTBF at least 1200hrs, with inspection interval min 500hrs) • Low maintenance and high robustness, with emphasis on capability to cope with oil pollution and flow variation, including ability to operate without oil for certain amount of time) • Capable to operate without wastegate and actuator • Low weight • Aeronautical certificability Project targets will be evaluated by performing testing on the gas stand modified to meet specific requirements of the project. After the tests Post Test Analysis will be performed to assess condition of the parts and create recommendation for further developments aiming on having turbocharger ready for certification and production.

Proton Exchange Membrane Fuel Cells are considered as one of the solutions enabling long-term sustainable transport, however, incumbent systems provide electric power outputs below 200 kW. To cater to the need of the heavy-duty transport sectors, the development of next generation of Fuel Cell systems aims at durable PEMFC stacks offering power output between 250 and 500 kW. To support this development, the H2UpScale project aims to design, build, test and validate key BoP components for PEMFC systems generating more than 250 kW electric power suitable for heavy-duty transport applications (aviation, maritime, on-road long-haul). H2UpScale brings together 3 research organisations, 2 academic and 11 industrial partners, including BoP manufacturers and OEMs. The project will identify application-specific requirements, that will then drive the requirements, development and optimization of 3 standards for modular and scalable PEMFC architectures ≥250kW (electrical power supply architectures & waste heat management system designs).The BoP components in focus include the hydrogen ejector, H2 recirculation pump, H2 leakage sensor, air compressor, cathode air filter and air humidifier, water separator, exhaust resonator, coolant heat exchanger and coolant medium. The targeted advancements for BoP components include efficiency and durability improvements, weight and volume reduction, and architecture simplification. The components will be designed to be compatible with both single- and multi-stack platforms, with scalability and modularity in mind, facilitating their integration into multi-MW scale systems. Selected full-scale BoP components will be validated on a Hardware-in-the-Loop test bench and a techno-economic analysis of the potential impact of the developed BoP components on the HD markets will be performed. With these main targets, the aim for H2UpScale is to provide critical technological bricks enabling the creation of a TRL7 demonstrator from 2027 onwards.
