Advancing zero-emission aviation with a focus on power, efficiency, and compliance.
H3 Dynamics has announced the launch of its AEROCELL 400KW hydrogen fuel cell, a system designed to meet the evolving needs of sustainable aviation. Delivering 0.4MW of electric power from a single stack, the unit offers twice the output of existing PEM fuel cells while reducing system weight by up to 50%.
This innovation highlights the growing potential of hydrogen technology in addressing aviation's carbon footprint challenges. The reduced weight and improved energy density could allow electric aircraft to achieve greater range and payload capacity, opening opportunities for a range of aircraft types, from regional airliners to urban air mobility vehicles.
AEROCELL 400KW and Aerospace Standards
Developed at H3 Dynamics’ Toulouse facility, the AEROCELL 400KW fuel cell is designed to meet the stringent safety and reliability standards required for aviation. The modular design enables configurations tailored to aircraft sizes, from small business jets to regional 50- to 100-seater planes.
Efforts to improve performance focus on reducing power module weight while maintaining functionality at high altitudes. By incorporating advanced materials and efficient system designs, the company aims to balance aerospace constraints with the performance demands of hydrogen propulsion systems.
Partnerships in Hydrogen Aviation
H3 Dynamics collaborates with key aerospace players, including Airbus UpNext, Pipistrel, and NLR, on projects ranging from unmanned systems to regional passenger aircraft. These partnerships demonstrate the potential of hydrogen fuel cells to transition aviation towards zero-emission operations.
The company also contributes to certification efforts, working with the European Commission’s Alliance for Zero Emission Aviation (AZEA) and EUROCAE’s WG-80 to align its fuel cell systems with future industry standards. This engagement ensures that the technology is scalable, standardized, and prepared for regulatory approval.
Focused on Scalable Solutions
By 2025, H3 Dynamics plans to open a certified production facility in France to support the integration of hydrogen-electric systems into aviation. This production capability aims to address the existing gap between off-the-shelf fuel cells and the highly regulated requirements of the aerospace industry.
"Hydrogen fuel cells have immense potential in aviation, but their adoption requires more than technical validation," said CEO Taras Wankewycz. "We are focused on creating a European value chain that meets both certification and operational needs, supporting the industry’s transition to zero emissions."
