Tailoring multicomponent nanometric alloys formed on active support for designing the stable anodes of Solid Oxide Fuel Cells

The aim of the research project entitled "Tailoring multicomponent nanometric alloys formed on active support for designing the stable anodes of Solid Oxide Fuel Cells" is to fabricate catalytically active anode materials with multi-component nanometric alloy precipitates and to study their impact on the long-term resistance of SOFCs to carbon deposition and poisoning by fuel impurities when directly fed with eco-fuels. Solid oxide fuel cells can provide a stationary source of energy in landfills, farms, etc. However, at present, investment costs related to system installation and the problem of cell degradation due to carbon deposition and sulfur poisoning are limiting the use of SOFCs fed with ecofuels on a larger scale. The implementation of the project will enrich the GUT equipment base and strengthen scientific cooperation with a foreign unit (CIEMAT).

Forming Ni-Fe and Co-Fe Bimetallic Structures on SrTiO3-Based SOFC Anode Candidates
Publication
- Fuels - Year 2024
The aim of this work was to verify the possibility of forming Ni-Fe and Co-Fe alloys via topotactic ion exchange exsolution in Fe-infiltrated (La,Sr,Ce)0.9(Ni,Ti)O3-δ or (La,Sr,Ce)0.9(Co,Ti)O3-δ ceramics. For this purpose, samples were synthesized using the Pechini method and then infiltrated with an iron nitrate solution. The reduction process in dry H2 forced the topotactic ion exchange exsolution, leading to the formation of...

Nanocrystalline cerium (IV) oxides doped with transition metals have gained significant interest recently, mostly in the field of catalysis. Herein, we present the comprehensive studies on ceria doped with 10 mol.% of transition metals (Mn, Fe, Co, Ni or Cu) synthesized by the reverse microemulsion method. The aim of this work is to study the properties of those materials with the use of different complementary methods like XRD,...
