Air Cooled (AC) Fuel Cells

Intelligent Energy's proprietary, high power density Air Cooled (AC) fuel cells have been designed for high volume manufacturing, whilst delivering low temperature operability and utilising simplified balance of plant. The overall result is compact stacks and system modules with fewer components, improved reliability and reduced system cost.

Designed to automotive standards for both mobile and stationary applications, the technology is for example appropriate for use as small fuel cell electric vehicle (FCEV) and UAV primary powerplant, battery electric vehicle range extender or stationary power generator.

Technology Summary

  • High power density
  • Provides clean DC power
  • Ambient air operation
  • High efficiency
  • Sub-zero capability
  • Compact metallic plate design
  • Eliminates the need for humidification systems – open cathode technology
  • Simple, low cost design
  • Reduced tooling costs
  • Stack can be scaled to meet customer power requirements
  • Flexibility in system packaging
  • Available in single stacks or system modules in the 1W to 20kW power range (can be combined for higher power applications)

Intelligent Energy’s Air Cooled fuel cells run on hydrogen and ambient air to produce clean DC power in a simple, cost-effective, robust and lightweight package. In the Air-Cooled fuel cell, heat from the fuel cell stack is conducted to cooling plates and removed through airflow channels, resulting in a simplified and cost effective power solution. The AC fuel cell technology can offer class leading sub-zero start-up. These systems are typically used in a wide range of portable, unmanned air vehicle (UAV) and stationary power applications, as well as two-wheel and small vehicle range extenders.

AC stacks and system modules are designed for high volume, low cost manufacturing, utilising modular architecture that can be readily modified to suit the intended application, form factor and power duty requirements.

Intelligent Energy has substantial experience in developing mass manufacture orientated fuel cell power systems. In addition, the company has developed and owns key intellectual property in system integration, balance of plant know-how, manufacturing know-how, proven software libraries for technology insertion, hybridisation and power management.

Precise fuel cell control is provided by on-board electronics and Intelligent Energy’s proprietary software algorithms which have been developed and refined over 30 years of fuel cell control experience.
