Застосування нанооксиду церію в твердооксидних паливних елементах

摘要: This review is analyzed the state of modern literature on nanoceria based materials application as components for solid oxide fuel cells. The principle operation cells, their classification and difference in constructions cells are described. unique redox properties nanosized cerium make this material promising (SOFC). Because high ionic conductivity, coefficient thermal expansion low activation energy at relatively temperatures, cerium-containing widely used a electrolyte. On surface CeO2 there many defects (which determined by concentration oxygen vacancies) that lead to electronic conductivity increases even temperatures (300 - 700 °C). can be increased doping divalent trivalent cations. electrical obtained nanocomposites dependent from synthesis methods, radii It explained effect transition size particles nanoscale region sample structure. Particular attention paid metal cations lanthanides characteristics material, namely, increase due vacancies. established development implementation main SOFC: electrolyte, anode cathode. Advantages using electrolytes over classical listed. was shown double triple reduces has positive its SOFC Composites, nanoscaled oxide, actively developed studied use electrodes Cerium-containing anodes resistant deposition carbon impurities, catalytic activity compatible with other components. Nanosized sprayed onto cathode prevent interacting prospects conversion chemical into analyzed.
