Cell & Stack Testing

We provide a wide portfolio of potentiostats, galvanostats and electronic loads for testing and characterization of fuel cells. Our main goal is to provide EIS analysis (Electrochemical Impedance Spectroscopy) for high-power hydrogen fuel cells, stacks, electrolyzers, redox-flow batteries, etc. Our devices can handle currents up to 2000 Amperes and power up to 20 kW. With a special boosting technique using external DC loads we can analyze hydrogen fuel-cell stacks up to 250 kW by means of EIS. 

We are constantly improving our products, we are now developing the 3rd generation of potentiostats and EIS analyzers. In the frame of our most important strategic R&D project, we are creating an electronic load with a new acquisition system for fuel-cell stacks up to 1000 cells, where all cells are analyzed simultaneously by impedance spectroscopy. This is important for a fast and most detailed end-of-line testing in the stack manufacturing process.
