Conflux Technology has unveiled a partnership with Australian aircraft manufacturer AMSL Aero to develop hydrogen fuel-cell cooling technology for AMSL Aero’s Vertiia electrical Vertical Take-Off and Landing (VTOL) aircraft.

In the initial project phase, Conflux created three heat exchanger designs aimed at minimising weight and volume while managing continuous heat loads and reducing aerodynamic drag. These designs are intended to support Vertiia’s hydrogen fuel cells, allowing flights of up to 1,000 km. The partnership has now entered its second phase, where Conflux will optimise and manufacture a complete proof-of-concept assembly for testing within the Vertiia aircraft.

Michael Fuller, CEO & Founder of Conflux Technology, says: “Hydrogen fuel cells represent a transformative technology in Australia’s pursuit of sustainable energy solutions. We are proud to incorporate our heat exchange technology to enhance the efficiency and performance of Vertiia’s hydrogen fuel cells. Together, we’re advancing innovation in creating world-leading sustainable air transport.”

AMSL Aero chairman Chris Smallhorn says: “In Vertiia we are building a hydrogen-electric aircraft that flies record-breaking distances at Formula 1 speeds, making Conflux Technology, with its storied history of innovation in motorsport and aviation, the perfect partner for us. AMSL Aero is committed to Victoria for future development of Vertiia and Conflux is one of Victoria’s industrial champions, making the Avalon Air Show the ideal place for us to unveil this partnership.”

The cooling systems developed by Conflux will manage high transient heat loads experienced during vertical take-off, landing and hover phases. Additive manufacturing enables lightweight, compact heat exchanger designs essential for hydrogen powertrains in aerospace applications.

Simon Coburn, hydrogen systems engineer at AMSL Aero, says: “We’re excited to work with Conflux, whose reputation for delivering at Formula 1 speed combined with AS9100D manufacturing and quality certification will be critical in enabling Vertiia to become the world’s first long-range passenger-capable hydrogen VTOL. Working together, we are pioneering a future where clean energy and cutting-edge engineering drive the aviation industry towards a greener and more sustainable future.”

Conflux’s aerospace solutions now extend beyond propulsion systems to include avionics, environmental, gearbox transmission, and power electronics cooling. Additive manufacturing continues to deliver performance advantages that traditional methods cannot match.
