HYDROGEN FUEL CELL AIR COOLED 500 Watt PEM Fuel Cell DYI

The H-500 PEM Fuel Cell is an air powered, air cooled and self-humidifying fuel cell. The H-500'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:
Connections/Tubing
Electronic valves
Electronic control box
500 watt stack with blower
Fuel cell ON/OFF switch
SCU ON/OFF switch
