The Horizon H-30 PEM Fuel Cell is a 30 Watt, air fed / air cooled, self-humidified hydrogen fuel cell suitable for many small projects and uses.  Because this fuel cell is air cooled there is not 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.

Projects might include: recharging for cell phone, power for a small RC car or boat, or just an economical way to begin experimenting with hydrogen fuel cells and their use and operation.
