Showcasing Innovation in Hydrogen Fuel Cell Technology for Aviation
The NIMPHEA project was proudly presented at the Vienna Aviation Days 2025, a high-level event organised by the ExFan project, bringing together major European research initiatives to explore the future of aviation propulsion systems.
At the event, the NIMPHEA coordinator presented a poster (see here: Poster_Nimphea_A0_OK) detailing the project’s cutting-edge work on the development of High Temperature Proton Exchange Membrane (HT-PEM) fuel cells tailored for aviation applications.
Poster Highlights
The poster highlights NIMPHEA’s focus on design, manufacturing, testing, and environmental assessment of next-generation High Temperature Membrane Electrode Assemblies (MEAs), especially its key innovations in:
- Electrode Development and characterization: Incorporation of corrosion-resistant carbon supports and mono-disperse platinum nanoparticles for improved catalyst performance.
- Durability & Efficiency: Integration of advanced materials to build effective and long-lasting MEAs under demanding aeronautical conditions.
- Manufacturing MEA: from lab scale surface (1.8 cm2) to representative MEA (160-180 cm2)
- Testing Capabilities: Use of a dedicated HT-PEM test rig to replicate real-world aviation scenarios.
- Life Cycle & Cost Assessments (LCA/LCC): Evaluation of environmental and economic performance from the MEA to the full propulsion system level.
A clear timeline guides the project from early component selection (2023) to full-scale MEA fabrication and testing by the end of 2026.

On June 11–12, 2025, the NIMPHEA project partners convened in Patras, Greece, for the fifth General Assembly, hosted by Advent Technologies. The meeting marked an important checkpoint in the project’s timeline, bringing together key stakeholders to evaluate progress and shape the path ahead.
Over the course of two days, consortium members presented technical developments, exchanged insights on ongoing challenges, and coordinated upcoming activities. A highlight of the meeting was the guided visit of Advent’s facilities in Patras Science Park, where participants explored the cutting-edge work being carried out on-site. The consortium also reached a consensus on risk identification for the upcoming year.
The Patras meeting reinforced the project’s collaborative momentum and underlined the shared commitment to driving innovation in hydrogen technologies across Europe.

The NIMPHEA project recently held its fourth General Assembly on December 9-10, 2024, at the Commissariat à l’Énergie Atomique et aux Énergies Alternatives (CEA) in Grenoble, France. This two-day meeting brought together partners from across the consortium to discuss the latest technical achievements and align on the project’s future direction.
Highlights of the meeting included updates on work packages, roundtable discussions including one on the development of next-generation components. A visit to the CEA laboratory provided partners with valuable insights into the project’s technical elements and advancements.
The event showcased the innovative and collaborative spirit driving the NIMPHEA project, paving the way for the next phase of progress in hydrogen technology.

On June 26th and 27th, the NIMPHEA project held its third General Assembly meeting at Fraunhofer in Pfinztal (Germany).
Partners were gathered to present their main technical achievements and results, offering vision about the project’s progression on the development of a new generation of HT-MEA.
The agenda was structured between presentations from WP leaders on their activities since the last General Assembly and roundtable discussions to go through current project issues: a discussion on the choice of the MEA architecture and the upcoming first Periodic Report.
Thank you to the whole NIMPHEA team which made this meeting a success with insightful technical discussions.
And special thanks to Fraunhofer for welcoming the consortium in Pfinztal !

On the 16th and 17th of November 2023, the NIMPHEA project held its second General Assembly meeting at the Centre National de la Recherche Scientifique (CNRS) in Strasbourg (France).
NIMPHEA General Assembly members
Partners presented their main technical achievements and principal results, offering vision about the project’s progression on the development of a new generation of HT-MEA.
It was also an opportunity for partners to discuss key technical issues and for the coordinator to update the consortium on ongoing administrative and communication activities.
At the end of the first day of meeting, participants were able to do a Lab tour organised by the CNRS.
The discussions showed a high level of commitment from all partners and a progression in line with the workplan and schedule.
Thank you to the whole NIMPHEA team which made this meeting a success with insightful technical discussions.
And special thanks to the CNRS for welcoming the consortium in Strasbourg !
