Nowadays, Solid Oxide Fuel Cells (SOFCs) operate at ≈98700℃.At such low temperatures, the electrolyte and the electrodes should exhibit very good properties.According to literature, doped zirconia materials (e.g.Yttrium or Scandium doped), prepared as a thin layer in order to further limit the ohmic loss, are classical electrolyte materials but some other ceramic materials showing proton conductivity can be also considered as potential electrolyte because of their better conductivity level are lower temperature.The most common SOFC anodes are cermets based on the electrolyte, which will bring the ionic conductivity, mixed with a large amount of metal (nickel) which will bring both the electronic conductivity and catalytic properties towards the hydrogen oxidation.That kind of anodes should present a thermal expansion coefficient very close to the electrolyte one for a good mechanical stability.The anode microstructure must be also optimised (porosity, phase distribution and particle size to (i) allow the gas flow through the entire anode and (ii) assure the cells mechanical stability.To increase the triple phase boundary (TPB), the nickel particles should be homogeneously spread throughout the ceramic matrix to form a continuous percolating network.In this presentation, after a briefly state-of-the art concerning high temperature anode materials for SOFC, we will report on the use of metallic Ni nanoparticles to improve both the properties of electrode materials (e.g.lanthanum manganite or titanate doped materials) and the proton conductivity of the ceramic electrolyte (e.g.BaCe0.9Y0.1O3-δ (BCY10)).In these materials, precipitation of Ni nanoparticles on the oxide grain surface catalyzes the hydrogen dissociation and can consequently facilitate the incorporation of protons in ceramic oxides.
