H-20 PEM Fuel Cell - 20W
Take your renewable energy projects to the next level with the H-20 PEM Fuel Cell (20W) — a powerful, efficient hydrogen energy system designed for advanced learning and performance. Delivering up to 20 watts of clean, reliable power, the H-20 is ideal for ambitious STEM applications, classroom integration, and hands-on exploration of cutting-edge fuel cell technology. Equipped with an integrated cooling fan for enhanced durability and thermal management, this fuel cell provides consistent output in both educational and prototyping environments. Built for flexibility and real-world relevance, the H-20 empowers students, educators, and innovators to push the boundaries of sustainable energy learning.
Fuel Cell Stack 20W
Hear from Our Customers:
“Horizon stacks are very flexible for research and education. It is very didactic. The students compare the properties of the fuel cell stack with increasing power and also gain knowledge about the construction of the fuel cell stack—not only for power but also for the electrical needs of the system, cooling, etc." - Professor Magdalena Dudek, AGH University of Science and Technology, Faculty of Energy and Fuels in Kraków, Poland
Fuel Cell and Hydrogen
Safety Requirements
Do not connect or disconnect power cables when the fuel cell stack is turned on. Warranty is void if the fuel cell stack is disassembled or otherwise altered. Hydrogen is a colorless, odorless, and flammable substance. Always operate and store the fuel cell stacks and hydrogen storage canisters in an area with ample ventilation. Fuel cell systems should always be equipped with a highly accurate hydrogen sensor to detect any leaking hydrogen within the system or from the hydrogen storage canister. Please refer to the H-20 User Manual to see a complete list of the safety requirements for the product.
