Recommended for use in small projects, the versatile H-12 PEM Fuel Cell is an air powered, air cooled and self-humidifying fuel cell. The H-12's air cooling feature renders bulky and inconvenient water cooling systems obsolete, allowing for a semi-integrated, efficient and reliable system. The H-12 comes equipped with an air blower, control electronics and a hydrogen supply valve. 

The H-Series PEM fuel cells are the most compact and the least heaviest fuel cell out in the world.


  • Integrated fan and casing
  • 12 watt stack with blower
