Project target is research and development of air supply modules for use in fuel cell systems.
The development is focused on two different power classes:
- 0,5 - 10 kW stack power
- 20 - 100 kW stack power
For the lower power range high speed side channel blowers with brushless DC-drivers are used. The drive electronics are completely intedrated. This gives a very compact and powerful blower with a wide range of available interfaces.
With 3 different drives a volume flow range between appr. 10 - 120 m3/h up to 400 mbar pressure difference is covered. To optimize efficincy it is possible to adapt the unit to the specific point / range of operation.
Power voltage: AC 90 - 264V 50 / 60 Hz or DC 24 / 48V
A humidifier can be adapted to the blower.
For the higher power range radial blowers with frequency controlled AC drivers are used. For the specific volumen flows different impellers areavailable. Testing of different type and arrangements of bearing are one of the main issues in this part of the project.
