The H-5000 PEM Fuel Cell (5 Kilowatt) is an air powered, air cooled and self-humidifying fuel cell. The H-5000'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.
