Research Project "MagiQ"
In the state project "MagiQ" funded by IB-Sachsen-Anhalt, we are developing measurement technology/sensor technology together with Fraunhofer IMWS for application in quality assurance of electrolysis stacks.
The goal is to characterize and find defects in electrolysis stacks without them being in operation.
For this purpose, we use our high-frequency magnetic field measurement technology.
The electrolysis stacks are subjected to a high-frequency alternating current and we measure the resulting magnetic field - precisely, contactlessly and non-destructively.
This method is unique so far and opens up new possibilities for mass production and maintenance of hydrogen electrolysis systems.
