QMS-FC - TEST BENCHES FOR FUEL CELLS

Test benches for fuel cells are available in the power ranges from
0.5 KW to 100 KW

Our test benches for fuel cells offer the following:

• flexible adaptation regarding your requirements (flow rates, pressure losses...)
• automated, unsupervised operation of the test bench by a control system with flexible setting of cycle and parameter
• storage and conditioning of measuring data according your request
• a completely validated safety and alarm processing concept
• large temperature ranges of the fuel cells media supply (e.g. cooling water from -40°C to 130°C)
• low-temperature cooling of the fuel cell and the cooling circuit to -40 °C for cold start tests
• cooling medium DI water or DI water/ethyl glycol - mixture
• high dynamics
• accurate pressure controls, gas flow without pulsation
• accurate temperature controls
• high-dynamic, exactly adjustable humidification regulated by direct-steam-proportioning
• different fuel cell operation modes on one test bench (e.g. Dead-end, recirculation...)
• reliable and verified safety engineering with:
  
  • 3 stages - alarm processing and notification of emergency by software
  • safety-relevant alarms are designed redundant by hard-wired emergency shutdown relays
  • inertization with nitrogen during activation of – emergency shutdown
  • packaging of the fuel cell in transparent and ventilated compartment
  • H2 detection, loss of ventilation sensor
