1.25 kW Closed-Cathode Fuel Cell Powerpack for UAVs : HYCUS X1
Summary
Closed-cathode type : Separation of channel for supply of reactant air and cooling air
The fuel cell powerpack rated output is 1.25, 1.6, 2.5, and 3.5 kW
HYCUS X series can be operated at minus 35 degrees Celsius
Composed of titanium separator
Stack warranty life time 3,000 hours
Moisture-free operation (No separate humidifier required)
CE-certificated product
Closed-Cathode Air-Cooled Fuel Cell Powerpack
HYCUS X models consist of closed-cathode type air-cooled fuel cells designed for demanding environments and compact applications.
Highly reliable stack performance suitable for long-duration continuous operation.
Operates efficiently at temperatures down to –35 °C.
No external humidifier required, enabling true moisture-free operation.
Designed with titanium separators for enhanced durability and reduced system weight.
The system can be configured with a dedicated blower-based air supply, and external air filtration can be applied to effectively remove dust and particulate matter before air is supplied to the stack.
This architecture enables stable and reliable operation in dusty and polluted environments, such as industrial sites, urban areas with high PM levels, construction zones, and desert-like conditions.
HYCUS X fuel cells offer long-lasting performance with a stack warranty life of 3,000 hours.
Their moisture-free operation, compact design, and filter-enabled air management make them ideally suited for integration into mobile, portable, UAV, and remote power systems.
HYCUS X is available in 4 variants :
Key features
Closed-Cathode Design
Independent air channels for reactant and cooling air ensure stable performance and increased stack reliability.
Fully operational in environments as low as -35°C, ideal for harsh climates.
Designed for moisture-free operation, eliminating the need for separate humidification systems.
Durable Titanium Separators
Increases system durability and reduces overall weight.
