20W PEM Fuel Cell
 Recommended for use in small projects, the versatile H-20 PEM Fuel Cell is an air powered, air cooled and self-humidifying fuel cell. The H-20's air cooling feature renders bulky and inconvenient water cooling systems obsolete, allowing for a semi-integrated, efficient and reliable system. 

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

Includes:
  • Miniature electronic valve
  • Control electronics
  • Integrated fan and casing 
  • Low pressure protection
  • 20 watt stack with blower


Average lead time is 2 weeks
