Fuel Cell System - Module

High efficiencies and low emissions make the fuel cell an interesting option for Auxiliary Power Units, APU. A couple of applications can take advantage of the short starting time and high dynamics of hydrogen powered fuel cell systems.

Modular concept

Today fuel cell systems usually are being de-signed specially for the specific application. The design of a modular system with very few and simple interfaces reduces that high effort to a minimum. The system is based on the 19“ standard, the system support is reduced to a 24 V voltage supply and a hydrogen supply connection.


The modular system design enables an easy integration to other systems. The 19” body fits perfectly for telecommunication purposes and building services. The system provides the full power after just a few seconds and is ready for long-term usage. With an operating level of 24 VDC and continuous power of 500 Watt there are several more applications which can be powered. Parallel connection of the modules is possible.

For education, research and development the measurement data and operating parameters can be monitored via digital port.

Characteristics of the module

  • Boverall size: 483 x 230 x 300 mm (l/w/x/h)
  • weight: approx. 17 kg
  • air cooled stack with 38 cells
  • hydrogen (3.0) / 2 - 6 barabs
  • power supply periphery: 24 VDC
  • output voltage: 20 VDC - 35 VDC
  • power: 500 W / max: 750 W
  • environment: 4 °C - 30 °C
  • start time approx. 2 sec.
  • analog and digital port (RS232
  • CE – approved


ZBT provides the module in a first step for test purposes. Continuative developments with project partners are possible.


The module was developed in the context of the project „Brennstoffzellen-Hybridsystem“ 286 ZBG, supported by “Industrielle Gemein-schaftsforschung” by BMWi via AiF.
