The impact of nanoparticles exsolved from double perovskite on the efficiency of biogas-fueled SOFC | Faculty of Applied Physics and Mathematics at the Gdańsk University of Technology

During the implementation of the project, a series of compounds with the general formula Sr₂M_xFe_1.5-0.75xMo_0.5-0.25xO_6-δ (SFM), where M = Co, Ni, Cu, x ≤ 0.2 will be synthesized and characterized. Under reductive treatment, the transition metals will be exsolved from a double perovskite lattice forming M-Fe nanoalloys, which will act as catalytically active centres for fuel oxidation. Then the composite of SFM and doped ceria will quasi-symmetrically deposited on the LSGM electrolyte, and the novel cell will be thoroughly examined when fueled with synthetic biogas. Furthermore, a long-term test will be performed to establish degradation rates and sulfur tolerance will be measured when fed with controlled addition of H₂S.

The implementation of the above research plan will provide an in-depth understanding of the mechanisms of formation of active nanoparticles on a double perovskite substrate and a thorough analysis of the properties of materials in working conditions with biogas.

The project will be implemented at the Institute of Nanotechnology and Materials Engineering of the Faculty of Applied Physics and Mathematics.

The project received funding in the amount of PLN 209 230. The duration of the project is 36 months.

Congratulations and best wishes of further success!
