Publications and projects

DENKweit's research and development activities in the B-Tech field combine innovative scientific work, practice-oriented research reports, as well as ongoing and completed funding projects.

The focus is on topics such as MFI (Magnetic Field Imaging), imaging magnetic field measurement, sensor-based measurement methods, and the transfer of scientific findings into industrial and medical applications.

The studies, whitepapers, and research reports published here provide detailed insights into our work on new measurement methods, algorithms, and system solutions.

In addition, we present national and international funding projects – in close cooperation with industry partners, research institutions, and universities.

01
Funding project

Research project “MagiQ”

MFIFraunhofer IMWSIB-Sachsen-AnhaltHydrogen

In the state project “MagiQ”, funded by IB-Sachsen-Anhalt, we develop measurement/sensor technology together with Fraunhofer IMWS for quality assurance of electrolysis stacks.

The goal is to characterize and find defects in electrolysis stacks without them being in operation.

The stacks are subjected to a high-frequency alternating current; 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.
