In the context of the energy transition and climate change, there is growing interest in the use of green energy sources. Compared to hydrogen, green ammonia offers various advantages such as greater energy density and easier liquefaction. Solid-state ammonia synthesis (SSAS) is an electrochemical process for the direct production of green ammonia from atmospheric nitrogen and water vapour. As part of the planned project by the Leibniz Institute for Plasma Science and Technology (INP), The Hydrogen and Fuel Cell Center (ZBT) and the Fraunhofer Institute for Laser Technology (ILT), innovative production processes for manufacturing such cells are being developed. This includes spray coating and magnetron sputtering of ceramic thin films on metal substrates and subsequent laser annealing of the deposited layers. Upon completion of the project, a high-performance thin-film-based SSAS cell and new insights into degradation under operating conditions should be available.
