EKPO Fuel Cell Technologies (EKPO) will exhibit its portfolio of high-performance fuel cell stacks and components at the Hydrogen Technology World Expo in Hamburg from October 20 to 22, 2026. At Booth 7H46 in Hall 7, the company will also present HyFleet, the world’s first road-legal hydrogen-powered side-by-side vehicle. The vehicle’s high-performance EKPO NM12 fuel cell stack is proving its capabilities under demanding real-world operating conditions, according to the company.
Drawing on extensive experience in developing and industrializing fuel cell technology, EKPO is advancing the use of hydrogen across a range of mobility applications. The HyFleet project, developed by BRP-Rotax in collaboration with industry and research partners, illustrates how this technology can also be used in demanding specialty vehicle applications. The side-by-side vehicle combines a range of up to 400 kilometers with a refueling time of approximately five minutes.
At the heart of the fuel cell system is EKPO’s high-performance NM12 stack. Delivering high power density, the stack provides the basis for the 90 kW fuel cell system, which achieves an efficiency of up to 60% and responds rapidly to changes in load. Extensive on- and off-road testing under real-world conditions demonstrates the system’s suitability for practical use. A passive hydrogen recirculation system developed in collaboration with HyCentA provides added robustness and efficiency. In this context, an innovative two-step needle ejector reduces mechanical complexity. With cold-start and freeze-start capability at temperatures as low as -20 degrees C, the system is also designed for winter and alpine conditions.
“HyFleet shows how we are applying our many years of fuel cell expertise to new mobility applications. Hydrogen is particularly well suited to demanding on- and off-road applications that require long operating hours and high availability. Our NM12 fuel cell stack, backed by our expertise in development and industrialization, helps our partners put this potential to work,” says Dr. Stefan Dwenger, Managing Director of EKPO Fuel Cell Technologies GmbH.
How this potential can be put to practical use is being tested under real-world operating conditions as part of the HyFleet initiative. The project is generating insights into hydrogen-powered specialty vehicles for use in agriculture, forestry, tourism, municipal services, and industry, among other sectors. HyFleet takes an integrated approach to operating hydrogen-powered vehicle fleets: the project considers every stage, from local green hydrogen production to the powertrain, vehicle, and scalable refueling infrastructure. The results also help guide further development and the technology’s use in additional applications.
“HyFleet has demonstrated that a hydrogen fuel cell powertrain can also work successfully in a compact special-purpose vehicle designed for off-road use. In EKPO, we have a partner that brought extensive experience in developing and industrializing fuel cell stacks to the project, along with technology tailored to our needs. EKPO thus played a key role in turning our vehicle concept into reality,” says Stefan Arndt, General Manager BRP-Rotax, VP R&D Powertrain.
With more than 20 years of experience in the field of fuel cell technology, EKPO combines extensive technical expertise with industrialization capabilities drawn from the automotive industry. Alongside HyFleet, EKPO will showcase fuel cell stacks and components for a range of mobile and stationary applications at the event in Hamburg. With power outputs ranging from 16 kW to more than 400 kW, the modular platforms are engineered for high power density, efficiency, and dependable operation. EKPO also develops customized stack solutions tailored to each customer’s system architecture and specific requirements.
EKPO’s portfolio extends to green hydrogen production, with metal bipolar plates that the company develops and manufactures for PEM electrolyzers. In this context, the company adapts its know-how in precision forming as well as coating and sealing technologies to the particular demands of electrolysis. The bipolar plates are engineered to withstand demanding operating conditions and support scalable industrial manufacturing.
The HyFleet project received funding through the Zero Emission Mobility program and was administered by the Austrian Research Promotion Agency (FFG). The original release can be viewed on www.newmediawire.com.
