Fuel Cell Stack 12W

Additional Information

While the H-12 can be purchased in standalone form, Horizon Educational recommends contacting us to build an entire package in order to more effectively integrate the product into your project.  Please click here to fill out a quote request form if you would like to create a whole package that includes the fuel cell stack and required auxiliary components.

While the H-Series fuel cell stacks are unable to offer an automatic level of continuous power, we do offer a DC-to-DC adapter enabling a continuous power output level from the fuel cell stack.

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.
