Horizon's new H-12 PEM Fuel Cell System is the lightest, most compact (and most competitively priced) 12W system in the world.  The H-12 Fuel Cell is a 12 Watt air fed / air cooled, hydrogen fuel cell suitable for many small projects and uses.  Because this fuel cell is air cooled there is no need for large, complicated, and expensive water cooling systems.  This semi-integrated unit is provided in kit format complete with air blower, control electronics and hydrogen supply valve.

List of components in the package:
  • 1 x 12W fuel cell stack (with integrated fan and casing)
  • 1 x silicon tube (OD 4 x ID 2.5mm), 50cm long
  • 1 x silicon tube (OD 6 x ID 3mm), 50cm long
  • 1 x filter
  • 2 x red plastic pin
  • 2 x inlet/outlet gas fitting (M3-4)
  • 1 x FC positive output line, 30cm long
  • 1 x FC negative output line, 30cm long
