LIVERMORE, Calif., Aug. 18, 2025 (GLOBE NEWSWIRE) -- Advent Technologies Holdings, Inc. (NASDAQ: ADN), an innovation-driven leader in the fuel cell and hydrogen technology sector, is supplying its proprietary membrane electrode assembly technology to Stralis Aircraft, based in Australia, for their hydrogen electric Beechcraft Bonanza aircraft.
Emory De Castro, Chief Technology Officer of Advent Technologies Holdings, Inc., stated, "we continue to work closely with the team at Stralis on their next generation high temperature (HT-PEM) fuel cells for their hydrogen electric propulsion system. Advent’s HT-PEM membrane electrode assembly is an integral part of the fuel cell, and our technology enables the engines to be efficiently cooled with smaller radiators that reduces weight and drag on the aircraft."
Stuart Johnstone, Chief Technology Officer and Co-founder of Stralis Aircraft, said: "We are proud to be working with Advent in the USA to develop our fuel cell system for aircraft. Thanks to this tech, our system is significantly lighter than existing alternatives, which is what is needed for aircraft. We enable aircraft to fly more than ten times further than battery-electric solutions at a lower cost than fossil-fuel-powered planes. We are already testing our hydrogen-electric propulsion system on the ground and plan to achieve first flight of our six-seat technology demonstrator aircraft later this year."

Hydrogen electric propulsion systems have fewer moving parts and operate at lower temperatures compared to existing aircraft engines, which is predicted to reduce engine maintenance costs by between 40-60%. Hydrogen-electric propulsion systems can replace batteries on existing electric aircraft and eVTOL, retrofit into piston or turboprop aircraft, be incorporated into clean sheet designs, or even serve as auxiliary power units (APUs) onboard larger aircraft.
Gary Herman, CEO of Advent Technologies Holdings, Inc., stated, "Our membrane technology is unsurpassed and offers a versatile clean energy solution across multiple industries including aviation, marine, automotive, and defense."
Advent Technologies Holdings, Inc. is a U.S. corporation that develops, manufactures, and assembles complete fuel cell systems as well as supplying customers with critical components for fuel cells in the renewable energy sector. Advent is headquartered in Livermore, CA, with offices in Athens and Patras Greece. With approximately150 patents issued, pending, and/or licensed for fuel cell technology, Advent holds the IP for next-generation HT-PEM that enables various fuels to function at high temperatures and under extreme conditions, suitable for the automotive, aviation, defense, oil and gas, marine, and power generation sectors.

Stralis Aircraft is based in Australia, and is aiming to be the world's leading emission-free aircraft company, producing high-performance, low-operating cost, hydrogen-electric propulsion systems and aircraft at scale. The propulsion system incorporates their proprietary high-temperature next-generation fuel cell system that is six times lighter than automotive fuel cell systems. Their hydrogen-electric aircraft will travel ten times further than battery-electric alternatives and will be cheaper to operate than fossil fuel-powered aircraft. Stralis has letters of intent to buy the aircraft from airlines across Australia, New Zealand, Asia, the USA, and Europe.
