Please try againCommercial and industrial UAVs are increasingly being deployed for logistics, infrastructure inspection, agriculture and other demanding applications. As flight-duration and payload requirements increase, many operators are encountering the practical limitations of battery-electric propulsion systems.The C2 Series was developed to meet these needs, providing a compact, lightweight fuel cell platform for UAV propulsion, portable power and off-grid energy systems.“Customers are asking for longer operating times and greater payload capacity without adding unnecessary weight and complexity,” said Daniel Zafir, Director, Business Development & Global Partnerships at Siltrax. “C2 brings together our silicon bipolar-plate technology and a purpose-built air-cooled architecture to provide a practical, simplified fuel cell system platform for these demanding applications.”A Different Approach to Air-Cooled Fuel CellsThe C2 Series is built around three principal design elements:Dedicated fans move ambient air through the stack’s cooling channels, removing the need for a separate liquid-cooling circuit and its associated pumps, coolant, plumbing and controls.Closed-cathode architectureUnlike conventional open-cathode air-cooled stacks, C2 separates the cooling airflow from the cathode reactant-air supply. Oxygen is channelled through the stack independently, allowing its flow, pressure and filtration to be managed separately and shielded from external air pollutants, increasing both the performance and durability of the overall system.The dead-end anode architecture supports efficient hydrogen utilisation while eliminating the need for a continuously operating hydrogen-recirculation circuit, further reducing balance-of-plant weight and complexity.Together with Siltrax’s proprietary silicon bipolar plates, these elements enable a compact fuel cell platform designed to balance performance, power density and durability without the complexity of a conventional liquid-cooled system.This advertisement has not loaded yet.This advertisement has not loaded yet, but your article continues below.The C2 Series supports power outputs from 2 kW to 6 kW, with a 3 kW reference architecture providing a defined starting point for customer evaluation and application integration. In addition, the C2 Series module can be operated in parallel, meeting power needs up to 24 kW.Beyond UAV propulsion, C2 can also be used for portable and off-grid power applications where conventional liquid-cooled fuel-cell systems can introduce unnecessary weight and maintenance requirements. Its simplified thermal management architecture makes the platform particularly suited to remote power, mobile generators, autonomous systems and other weight sensitive applications.3.6 kW Rated Power>1.5 kW/kg Gravimetric Power Density-20~40°C Ambient TemperatureThe C2 Series launch follows Siltrax’s recent entry into the U.S. market as the company expands its commercial presence and customer partnerships across the Americas.Siltrax will showcase the C2 Series at Stand 7F30-5 at the Hydrogen Technology World Expo, held at Hamburg Messe, Germany, from 20–22 October 2026.For product specifications, evaluation opportunities or commercial enquiries, contact info@siltrax.netAbout SiltraxHeadquartered in Sydney, Australia, with a presence across the Americas, Siltrax is advancing hydrogen technology through silicon-based PEM fuel cells and electrolyzers.
