H-12 PEM Fuel Cell - 12W
Power innovation in real time with the H-12 PEM Fuel Cell (12W) — a high-performance, compact energy solution designed to bring hydrogen learning to life. Delivering a reliable 12 watts of clean power, this cutting-edge fuel cell enables students, educators, and hobbyists to explore sustainable energy principles hands-on. Perfect for integration into science kits, classroom experiments, or custom applications, the H-12 offers real-world insights into hydrogen technology and PEM (Proton Exchange Membrane) fuel cell functionality.
Enhanced with an integrated fan for optimized cooling and performance, the H-12 ensures durability and efficiency during extended use.
Fuel Cell Stack 12W
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-12 User Manual to see a complete list of the safety requirements for the product.
