The very high reliability and low maintenance costs of the HyModule® fuel cell system solution, which is ready for integration, compared to conventional diesel and/or battery use, speak in favor of hydrogen fuel cell technology as an energy source in the context of an emergency power application or in use as a grid backup system.

With hydrogen as the energy carrier, almost unlimited bridging times can be realized by the Proton Motor product HyModule® in the HyModule® S4 and HyModule® S8 size classes as a modern, exhaust- and noise-free power generator.

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

In addition, many other applications can be realized with HyModule® S4 / S8 where an efficient and environmentally friendly energy supply is required.
