H-20 PEM Fuel Cell - 20W
20W PEM Fuel Cell Stack Overview
At 20-watts this fuel cell stack remains on the entry-level side of the fuel cell stack spectrum for integration into proof-of-concept projects. The minimal power envelop provides an easy-to-use product. A miniature electronic valve, control electronics, integrated fan, and low voltage protection provide useful features that enable this fuel cell stack to accelerate project development.

While the H-20 can be purchased without any supporting components, Horizon Educational recommends contacting us to build a total package in order to more effectively integrate the product into your project. You can click here to fill out a quote request form if you would like to create a complete package that includes the fuel cell stack and required supporting components.
Fuel Cell and Hydrogen
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.
You can read posts to our blog to learn more about the way that our low wattage fuel cell stacks are changing this world and helping students to learn about hydrogen and fuel cells. Our blog is also a great way to get caught on H2GP season updates, and other fuel cell electric vehicle racing updates.
