5kW Liquid Cooled FC System VL-Series

This fuel cell stack is the entry model of the liquid cooled fuel cell stacks from Horizon Fuel Cell Technologies.  This fuel cell stack is the lowest minimum power we recommend for use in forklifts, small tractors, and other low-end commercial and industrial applications.  The liquid cooling of a fuel cell stack enables it to operate in more variable environments where a vehicle, like a forklift, may frequently go from having a full load to ferrying zero cargo.  In such use cases the liquid cooling helps the fuel cell stack to maintain a more consistent optimal temperature, which enables the stack to operate for more hours (even continuously) throughout a day.  Because of the commercial and industrial use cases for liquid cooled stacks they also offer more power than air cooled stacks.

Additional Information

It is important to note that the liquid cooled fuel cell stacks which Horizon sells are systems instead of either a fuel cell stack or a fuel cell stack and a controller.  Liquid cooled fuel cell stacks typically come 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.

Please fill out a quote request form so that we can set proper delivery and pricing expectations.  It is important to note that liquid cooled fuel cell stacks are larger and heavier than air cooled stacks, because the liquid cooling does add weight to a fuel cell system.  If you are uncertain whether a 5kW air cooled stack will work better for your project, then please feel free to mention that in the quote request form so that we can cover that issue with you.

List of VL-05 components and their functionality:

  • Air filter (Prevents damaging size particles from entering fuel cell)
  • Air flow meter (Monitoring feedback of air flow)
  • Humidifier (Adds humidity to the air entering the stack)
  • Radiator (Removes excess heat from the system
  • Ion Exchange (Absorbs ions in the coolant and reduce the conductivity of the coolant)
  • Controller (Control system, system and vehicle communication)
  • Fuel cell stack (Oxygen and hydrogen react to produce power)
  • Fill water tank (Filling water and purge air for the fuel cell system)
  • Fuel cell 24V water pump (Powers the cooling cycle of the fuel cell)
  • Constant voltage DC (Charge the 48V power battery)
  • Blower (Provide air for the system)

In addition to the above components, the fuel cell system is also equipped with some sensors to feed back the temperature, pressure and humidity signals of the controller system during operation.
The internal oxygen supply system and cooling system components of the system also need to be connected with silicone tubes and multi-way joints to ensure the flow of fluids in the system.
The fixing of the various parts of the system requires the support of a bracket, and the whole system needs a fixed frame, which is connected and fixed together by the frame. Finally, many electrical parts in the system need to be connected with high-voltage wiring harness or low-voltage wiring harness.
