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.
Average lead time is 2 weeks.
