Please note that the current lead time for the Horizon H-300W PEM Fuel Cell is 10 weeks.

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.
