- In the course of the project, the technology readiness level (TRL) of reversible AEM electrolysis (rAEM) should be raised from TRL 2 at present to TRL 5
- The project goal is a functioning rAEM short stack with 10 kW electrolysis capacity as a laboratory setup
- and also the development and testing of a novel reversible electrolysis technology for efficient harvesting of hydrogen from renewable energies and its reconversion
This AEM (anion exchange membrane) technology works with a similar concept to the classic PEM (proton exchange membrane) technology, but far more cost-efficient materials for the membrane can be used, catalysts (precious metal-free), and bipolar plates (titanium-free).
The particular challenges are to be found:
- in improving the chemical stability of AEMs even at high current densities;
- in testing suitable electrocatalysts, which are suitable for both the electrolysis and the fuel cell mode; and
- in the design and testing of a cell structure suitable for reversible operation.
Fraunhofer IWES research topics:
- MEA production and laboratory tests (electrolysis and fuel cell)
- Material diagnostics (in cooperation with Fraunhofer IMWS)
- Simulation for flow field optimization (in cooperation with Fraunhofer IMWS / CSP)
