JEKTA, the Switzerland-based developer of the PHA-ZE 100 amphibious aircraft, has selected ZeroAvia’s fuel cell power generation system (PGS) technology to demonstrate the concept of a fuel cell variant of its electric amphibious flying boat design, with a view to line-fit of the system as the PHA-ZE 100 variant comes to market.

While battery technology continues evolving, JEKTA is committed to exploring all potential options that will increase the range and payload of its zero-emissions aircraft. Powered by ZeroAvia’s fuel cell PGS, it is anticipated the PHA-ZE 100 will achieve a range of up to 500 km or 600 km and increase the payload by up to 1 ton, adding even more capability to the airframe. Operating and maintenance costs can also be lowered with a H₂ fuel system supporting a life of up to 20,000 hours. Through close cooperation, JEKTA and ZeroAvia will develop and certify an integrated PGS, including inverters, other electronic components, and a H₂ tank and fuel system.

George Alafinov, CEO, JEKTA Switzerland, said, “By working with ZeroAvia and defining a suitable fuel cell system, we can offer our potential operator clients the choice of two fuel sources. The H₂ system delivers a viable alternative to electric battery power that promises a significant increase in the range of our PHA-ZE 100, which will suit operators serving longer regional routes. In contrast, the battery power option will suit shorter-range missions and operators flying in locations where electric power is more cost-effective and accessible.”

“ZeroAvia holds a strong market position with secure financing, an impressive set of customer commitments and well-developed infrastructure, which all contributed to our decision to work with them.”

ZeroAvia is already flying a prototype of its entire H₂-electric powertrain (ZA600) in a 19-seat testbed aircraft. It has developed a range of flexible low-temperature proton exchange membrane (LTPEM) PGS solutions and novel high-temperature PEM (HTPEM) fuel cells for H₂-electric aerospace applications.

Val Miftakhov, Founder & CEO, ZeroAvia, said, “The JEKTA team shares our vision of introducing clean aircraft propulsion systems into commercial operations. We are noting a resurgence in the seaplane market, and we’re excited to work with an innovative company that is leading and shaping the future of amphibious aviation. We see the huge potential for creating zero-emission amphibious flights, and we believe H₂-electric propulsion will play a big role in this market.”
