Hydrogen Propulsion
for a Sustainable
Aviation Future
Zephirion converts standard two-passenger aircraft to zero-emission hydrogen fuel cell propulsion systems, revolutionizing the future of flight.
Our Technology
How We Transform Aircraft
How It Works
Our hydrogen fuel cell system converts hydrogen into electricity through an electrochemical reaction, with water vapor as the only byproduct. This electricity powers efficient electric motors that provide thrust. The system integrates seamlessly with existing aircraft structures, maintaining or improving performance while eliminating emissions.
Key Components
- Hydrogen Storage: Lightweight, pressure-optimized carbon fiber tanks
- Fuel Cell Stack: High-efficiency PEM cells with advanced cooling
- Electric Motors: Lightweight, high-power density motors
- Power Management: Advanced electronics for optimal energy use
