HyFrame® is a modular and universal hydrogen fuel cell system for stationary applications with the Proton Motor stack module as the high-tech core element. HyFrame® was specially developed by Proton Motor as a product innovation and is manufactured to order.

In addition to the installed stack module, the fuel cell system already contains the following components:

  • Supply units for hydrogen
  • Supply units for reaction air
  • Cooling circuit
  • Control
  • Stress distribution

Several HyFrames® can be connected and operated in parallel to achieve higher outputs.

Typical applications:

  • Interlockings / Railway application
  • Telecommunications / Radio Application
  • Securing critical infrastructures
  • Industry and data centers
  • Energy self-sufficient residential buildings and industrial plants
  • Regenerating hydrogen from renewable sources
  • Off-grid power supply (stand-alone solution)
  • Grid-connected systems for emergency power supply or grid support
