Résumé

Highly sinterable yttria-doped ceria powder (YO1.5)x (CeO2)1 − x (x = 0.1–0.33) was fabricated by an optimized coprecipitation route. Compacted bodies could be sintered to impermeability at 1200 °C and near full density at 1300 °C, among the lowest temperatures reported for doped ceria densification. Ceria diffusion is important above 1400 °C. Excellent conduction properties were observed: high ionic conductivity (6.5 S m−1 at 750 °C for Ce0.8Y0.2O1.9), low activation energy (0.7 eV) and vanishing grain-boundary resistance

Pile à combustible à oxyde solide

Les piles à combustibles à oxydes solides (ou SOFC selon l'acronyme anglais de Solid oxide fuel cells) sont prévues essentiellement pour les applications stationnaires avec une puissance de sortie allant de 1 kW à 2 MW. Elles fonctionnent à très hautes températures, typiquement entre et (723 et 1273 K). Leurs rejets gazeux peuvent être utilisés pour alimenter une turbine à gaz secondaire afin d'accroître le rendement électrique.

Electrical resistivity and conductivity

Electrical resistivity (also called volume resistivity or specific electrical resistance) is a fundamental specific property of a material that measures its electrical resistance or how strongly it resists electric current. A low resistivity indicates a material that readily allows electric current. Resistivity is commonly represented by the Greek letter ρ (rho). The SI unit of electrical resistivity is the ohm-metre (Ω⋅m).

Glossary of fuel cell terms

The Glossary of fuel cell terms lists the definitions of many terms used within the fuel cell industry. The terms in this fuel cell glossary may be used by fuel cell industry associations, in education material and fuel cell codes and standards to name but a few. Activation loss See overpotential Adsorption Adsorption is a process that occurs when a gas or liquid solute accumulates on the surface of a solid or a liquid (adsorbent), forming a film of molecules or atoms (the adsorbate).
