“Advent Technologies, Stralis Announce Collaboration to Advance Hydrogen Electric Flight”
Advent Technologies Holdings, a leader in the fuel cell and hydrogen technology sector, is supplying its proprietary membrane electrode assembly to Australia-based Stralis Aircraft, for its hydrogen electric Beechcraft Bonanza aircraft, reports a press release.
The release explains, “Hydrogen electric propulsion (HEP) 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 and 60 percent.”
It continues, “HEP systems can replace batteries on existing electric aircraft and eVTOL, retrofit into piston or turboprop aircraft, and be incorporated into clean sheet designs or even as auxiliary power units onboard larger aircraft.”

Hydrogen Propulsion System
Emory De Castro, CTO of Advent, commented, “Our next generation high temperature membrane electrode assembly is an integral part of the fuel cell, and this technology enables the engines to be efficiently cooled with smaller radiators that reduces weight and drag on the aircraft.”
Stuart Johnstone, CTO and co-Founder of Stralis, added, “Thanks to this tech, our system is significantly lighter than existing alternatives, which is what is needed for aircraft. This enables our craft 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.”
