High-Power Hydrogen Fuel Cell Systems for Large Commercial Aircraft

transportTestedTRL 5

Imagine taking the battery technology from a hydrogen car and scaling it up to power a giant plane. Instead of just moving a small car, this tech aims to push a 100-passenger aircraft through the sky. It uses clever 3D-printed cooling parts and new materials to keep the system light and from overheating.

The business problem

What needed solving

Current automotive fuel cells are limited to 100 kW, which is insufficient for aircraft. Aviation requires multi-MW power that can handle extreme temperatures and pressures while remaining lightweight and safe.

The solution

What was built

A full-scale 2-PC demonstrator and test report. This includes new catalysts, membranes, 2-phase cooling systems, and 3D-printed heat exchangers.

Who can put this to work

Aerospace Manufacturing
enterprise
Target: Aircraft OEM

If you are an aircraft manufacturer dealing with the weight and heat of electric engines — this project developed a multi-MW power generation system that can propel a 100-passenger plane for 1,000 nautical miles.

Advanced Manufacturing
SME
Target: 3D Printing Specialist

If you are a component manufacturer dealing with inefficient heat rejection in engines — this project developed additive manufactured heat exchangers that reduce drag and weight while increasing cooling capacity.

Energy Systems
mid-size
Target: Fuel Cell Stack Producer

If you are a fuel cell producer dealing with the limitation of 100 kW automotive systems — this project developed catalysts and membranes that enable a power range of over 2 MW for aviation standards.
