As a part of the New Energies Research Center (NERC), a joint initiative from FAPESP and Shell, this Research Division 3 - Methane to Products (RD3) is built to grow as a world-class scientific center for research on advanced technologies for methane conversion to high-value products. In this context, RD3 addresses potentially disruptive technologies to tackle methane conversion beyond tr…
Nowadays, the research on micro solid oxide fuel cells allows to preview a new branch of investigation on proton conductors based on lanthanide (Y and rare earths) doped barium zirconate and cerate. These materials exhibit unique properties such as high proton conductivity at temperatures lower than those of the traditional oxide ion conductors. Relevant experimental results for oxide ion…

In this work, the effects of grain size on microstructural, electrical, and mechanical properties in fully dense nanostructured scandia-zirconia ceramics obtained by Spark Plasma Sintering will be investigated. Due to recent advances in this sintering technique, it is finally possible to obtain nanostructured ceramics with unique and unexpected properties for some classes of materials, su…
In this work, the effects of oxide additives (dysprosium and niobium oxides) on scandia-stabilized zirconia will be investigated aiming to stabilize the cubic phase at room temperature and to suppress the characteristic cubic-rhombohedric phase transformation. The effect of the particle size on the phase transition will be also subject of this study, by the synthesis and structural charac…
This proposal focus on the synthesis and characterization of thin films based on La0.7Sr0.3MnO3 (LSM) deposited on metallic substrates based on commercial ferritic steels STS 444-17%Cr e STS 446-23%Cr (STS- stainless steel) used as interconnectors in Solid Oxide Fuel Cells (SOFC). Substitution of the usual ceramic interconnector based on LaCr03 by the metallic interconnector based on ferr…
Scandia-zirconia (ScZ) has a great technological interest for solid electrolyte applications due to the highest ionic conductivity among zirconia-based ceramics. However, ScZ usually requires high temperatures (> 1600 °C) to achieve 95% relative density by conventional sintering. Fully dense nanocrystalline ScZ specimens were obtained by recently proposed deformable punch spark plasma sin…
In this work, as complementation of current doctoral project, the thermodynamic of zirconia-scandia system is proposed to be investigate in more detail. The phase stability of zirconia-scandia system will be investigated based on thermodynamic data collected by water adsorptionmicrocalorimetry and high temperature oxide melt solution in order to create an unprecedentphase diagram at the n…
The reduction of the operating temperature of solid oxide fuel cell (SOFC) to less than 800°C allows the use of metallic interconnects in planar SOFC systems. Metallic interconnectors exhibit many benefits, including increased thermal and electrical conductivity, good mechanical strength and low manufacturing cost. This proposal focuses on the synthesis and characterization of thin films …
