Stargate Hydrogen signs MoU with Saudi R&D authority to accelerate green hydrogen
11 September 2025Advent Technologies has advanced its collaboration with Airbus by delivering redesigned high-temperature membrane electrode assemblies (MEAs) for hydrogen aviation applications.
By reconfiguring the MEA design and introducing targeted hardware tweaks, the fuel cell technology company achieved higher power density and improved its fuel cell system efficiency.
The gains ensure the fuel cell engines can be cooled with smaller radiators to reduce both weight and drag on an aircraft. Therefore, this supports more efficient hydrogen-electric propulsion.
Beyond aviation, Advent sees the redesigned MEAs as a stepping stone toward applications in defence, heavy-duty mobility and off-grid power generation.
