Perfect for medium sized projects, the versatile H-300 PEM Fuel Cell  is an air powered, air cooled and self-humidifying fuel cell. The H-300's air cooling feature renders bulky and inconvenient water cooling systems obsolete, allowing for a semi-integrated, efficient and reliable system. 

The Horizon H-Series PEM fuel cells are the most compact and the least heaviest fuel cells on the market.

Includes:

  •  Connections/Tubing
  •  Electronic valves
  •  Electronic control box
  •  300 watt stack with blower
  •  Fuel cell ON/OFF switch
  •  SCU ON/OFF switch


Average lead time is 2 weeks.
