10kW Liquid Cooled FC System VL

This is the second of two entry level products for liquid cooled fuel cell stacks.  With a 10kW power envelop this fuel cell stack is an ideal product for electrifying all-terrain vehicles, tractors used in agriculture, and it is even ideal for switching golf carts to being electrified using fuel cells.  With a fuel cell electric golf cart fleet, golf course owners no longer have to deal with hours of downtime due to charging the large battery packs that golf carts traditionally have used.  This fuel cell stack product also works well at the college and university level in helping students to learn about current fuel cell stack technology.  It can be easily integrated into a common platform, like a golf cart, which enables professors to effectively pair in-classroom learning with an easy practical exercise.

Additional Information

As with other liquid cooled fuel cell stacks, this fuel cell stack is considerably heavier than air cooled stacks.  The following items are often included with a liquid cooled fuel cell stack from Horizon: 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 submit a quote request form in order to obtain additional information about this product.  This will also provide you with an opportunity to provide details on the project you are working on that needs a fuel cell stack, and with that additional information we may be able to recommend other components you will need to expedite the completion of your project.

List of VL-10 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.
