New research at DTU Energy under the Technical University of Denmark has created a stir in the fuel cell research community, where their new equipment can: measure on significantly larger fuel cells, more cells, and provide more accurate data in a shorter time.
The press release from DTU reports that PhD student Rasmus Rode Mosbæk at DTU Energy has installed new equipment, which included the IM6 from Zahner, and developed new methods to measure impedance, i.e. frequency dependent electrical resistance of fuel cells, making it possible to measure both the individual fuel cells and the entire fuel cell stack all at once and get significantly better data on top.
"It's basically better equipment and changed measurement geometry... we have gone from being able to measure at 16 cm2 cells to 90 cm2 at present; also we are able to record parallel impedance data, allowing us to do simultaneous measurements on all 16 fuel cells plus the entire stack, i.e. 17 measurements in total all at once."," explained Rasmus Rode Mosbæk.
Zahner's Managing Director, Dr Hans Schaefer, said, 'Zahner has been committed to building high quality uniquely parallel impedance spectrometers for the last 30 years, as well as providing highly technical after-sales support from our world leading electrochemical team'.
"Previously we could only measure one cell at a time and it took 13 hours to measure the 16 cells and the whole stack this way.. With the new equipment we can measure 16 cells and the entire stack in half an hour"
