The Horizon H-1000 PEM Fuel Cell is a 1 Kilowatt (or 1000 Watts), 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.

List of components in the package:
  • 1 x 1000W fuel cell stack (includes supply valve, purge valve, blower)
  • 1 x controller (includes short circuit unit) and this module is also known as electronic control box
  • Connections and tubing
  • Electronic valves
  • Fuel cell ON/OFF switch
  • SCU ON/OFF switch


The controller requires an external power supply of 13 volts and of up to 8 amperes. During the operation of the stack, the controller would not be consuming 8 amperes continuously.

Polarization Curves

Polarization curves (also known as fuel cell performance curves or IV curves or IE curves) are given both in the user manual and the brochure (see the links for PDF files below).
