30kW Liquid Cooled FC System VL-Series

This is the entry-level fuel cell stack for the mid-range liquid cooled fuel cell stacks that Horizon Fuel Cell Technologies offers.  These fuel cell stacks offer the ability to electrify boats, farm equipment, and other mobility applications.  In a place like California where laws and executive orders have been put into place to eliminate fossil fuel use in new cars and small engines, the VL-30 fuel cell stack offers individuals and companies the ability to convert vehicle fleets to a zero emission profile. 


30kW Liquid Cooled Fuel Cell VL-Series

Additional Infromation

Using this fuel cell product would enable fleets that undergo such a conversion to maintain the level of power they are used to with the benefit of being environmentally friendly.  Depending on the location there may already be a local hydrogen dispensing station, but if there is not one available a company like BayoTech can help to setup a refueling supply to ensure a painless conversion to the use of this fuel cell stack.

If you are looking to replace a current diesel or gasoline engine with a fuel cell stack or if you are looking to pursue a more ambitious project, then please complete a quote request form with the information relating to your project.  This will enable us to better meet your needs as well as set proper delivery expectations for the fuel cell system.  In keeping with other liquid fuel cell stacks this stack comes with an air filter, air flow meter, hydrogen intel solenoid valve, humidifier, throttle valve, radiator, ion exchange, controller, fuel cell stack, fill water tank, fuel cell 24V water pump, constant voltage DC, and blower to bring air into the fuel cell stack

List of core VL-30 components and their functionality:

  • Air filter (Prevents damaging size particles from entering fuel cell)
  • Air flow meter (Monitoring feedback of air flow)
  • Hydrogen heat exchanger (Increase the temperature of hydrogen)
  • Intercooler (Reduce the temperature of the air entering the stack)
  • Humidifier (Adds humidity to the air entering the stack)
  • Throttle (Adjust the internal operating pressure of the stack)
  • PTC heater (Heating of low temperature cold start)
  • Water tank (Refill water to and exhaust the system)
  • Deionizer (Absorbs the ions in the coolant, reducing the conductivity of the coolant)
  • Water pump (Power the cooling system)
  • Low voltage distribution box (Provide low voltage distribution to the system)
  • Controller (Control system, communication between system and vehicle)
  • Fuel cell stack (Oxygen and hydrogen react to produce power)

Hydrogen Blog

One of the best ways to see the power and value of hydrogen fuel cells is to follow our Horizon Hydrogen Grand Prix series.  Each season high school students from around the world put their remote-controlled fuel cell electric vehicles through a series of endurance races.  It is the ultimate FCEV racing challenge, and along the way students get to learn about batteries, fuel cells, and electronics in general.  This enables them to have workforce-ready knowledge and skillsets that organizations around the world can use to create their own next generation FCEVs and other zero emission products.

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 30 User Manual to see the full list of the safety requirements for the product.
