The Horizon H-500 PEM Fuel Cell is a 500 Watt, air fed / air cooled, self-humidified hydrogen fuel cell.  Because this fuel cell is air cooled there is no need for large, complicated, and expensive water cooling systems.

Horizon H-Series PEM fuel cells are semi-integrated, efficient, reliable systems that minimize the use of peripherals.  As such, they are the most compact and lightweight fuel cells around the world.
