50kW Liquid Cooled FC System VL-Series

This is the second fuel cell stack of the mid-range fuel cells that Horizon offers, and its power profile positions this fuel cell stack well to be used in a number of mobility applications.  It is possible to use this fuel cell system in forklift operations, but the possibilities also extend to more demanding tasks in agriculture and construction.  With this kind of fuel cell stack it is possible to create a full range of zero emission construction vehicles, and the operators of these vehicles will benefit from the low noise profile that is a hallmark of hydrogen fuel cell technology.

For vehicle enthusiasts who love to modify vehicles of all kinds, this fuel cell stack offers a lot of possibilities.  It can be used to breath zero emission life back into an old car or truck, or it can be used as a fun experiment at creating a homemade zero emission vehicle (ZEV)!

University Note

For colleges and universities looking to expand their hydrogen and fuel cell curriculum with additional tools, Heliocentris offers products that are designed to be integrated into university classes.  Like the products that Horizon Fuel Cell Shop offers, the Heliocentris Academia International products pair multiple renewable energy sources like fuel cells, solar panels, and wind turbines in order for students to learn more about how using multiple renewable energy sources can work together to achieve zero emission communities.  Heliocentris products can also be purchased through our Fuel Cell Shop, and you can also go to the website for Heliocentris in order to learn more about the products that it offers.

Fuel Cell and Hydrogen

Safety Requirements

Do not attach or detach power cables when the fuel cell stack is turned on.

Warranty is void if the fuel cell stack is dismantled or otherwise modified.

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 hydrogen that has escaped within the system or from the hydrogen storage canister.

Please refer to the VL II-40M User Manual to see the full list of the safety requirements for the product.
