For civil and military purposes, 1-50 kW open cathode and dead-end PEMFC stacks and systems with liquid or air cooling, and with metallic or composite graphite bipolar plates are being developed.  

Major Features:

  • Custom production in the range of 1 - 50 kW
  • Quick start-up (ideal ambient temperature ≈25 sec / cold ambient temperature ≈50 sec) and shut-down procedure
  • Low pressure drop with unique bipolar plate design
  • Wide operating conditions with liquid coolant
  • Environmental tolerance solutions thanks to its novel design
  • Extended specific power (kW/l) and power density (kW/kg)
  • Integrated cell potential monitoring
