PM Module S4 – the modular and all-purpose fuel cell system for stationary applications

The heart of the Proton Motor technology is the stack module, which is adapted to the power range. It is specially developed and manufactured by Proton Motor. In addition to the stack module, the fuel cell system already contains supply units for hydrogen and reaction air and a primary cooling circuit. The fuel cell system has a modular structure and can be interconnected to achieve higher performance. It is flexible and adaptable to multiple applications as well as reliable and predictable thanks to PM’s all-round services. Individual customer applications and exclusive system requests can be fulfilled. Universal 19 inch ready to integrate fuel cell modules are suitable for the power class up to 8 kW in stationary use

Typical areas of application:

  • Emergency power supply for:
    • Interlockings / Railway application
    • Telecommunications / Radio application
    • Securing critical infrastructures
    • Industry and data centers
  • Applications in combination with energy storage systems:
    • Energy self-sufficient residential buildings and industrial plants
    • Regenerating hydrogen from renewable sources
  • Off-grid energy supply (island solution)
  • Grid-connected systems for emergency power supply or grid support.
