Reduction of CeO

Frontiers of Chemical Science and Engineering 2013, Volume 7, Issue 3,   Pages 249-261 doi: 10.1007/s11705-013-1333-6

Abstract: Reduction behavior of pure and doped CeO , the multi-phase La Sr CoO ? CeO , La Sr MnO ? CeO , and La Ni Fe O ? CeO composites, was studied under hydrogen containing atmosphere to address issues related to the improvement of electrochemical and catalytic performance of electrodes in fuel cells. The enhanced reduction of cerium oxide was observed initially at 800°C in all composites in spite of the presence of highly reducible transition metal cations that could lead to the increase in surface concentration of oxygen vacancies and generation of the electron enriched surface. Due to continuous reduction of cerium oxide in La Sr CoO ? CeO and La Sr MnO ? CeO (up to 10 h) composites the redox activity of the Ce /Ce pair could be suppressed and additional measures are required for reversible spontaneous regeneration of Ce . After 3 h exposure to H -Ar at 800°C the reduction of cerium oxides and perovskite phases in La Ni Fe O ? CeO composites was diminished. The extent of cerium oxide involvement in the reduction process varies with time, and depends on its initial deviation from oxygen stoichiometry (that results in the larger lattice parameter and the longer pathway for O transport through the fluorite lattice), chemical origin of transition metal cations in the perovskite, and phase diversity in multi-phase composites.

Latest development of double perovskite electrode materials for solid oxide fuel cells: a review

Frontiers in Energy 2019, Volume 13, Issue 4,   Pages 770-797 doi: 10.1007/s11708-019-0651-x

Abstract: Recently, the development and fabrication of electrode component of the solid oxide fuel cell (SOFC) have gained a significant importance, especially after the advent of electrode supported SOFCs. The function of the electrode involves the facilitation of fuel gas diffusion, oxidation of the fuel, transport of electrons, and transport of the byproduct of the electrochemical reaction. Impressive progress has been made in the development of alternative electrode materials with mixed conducting properties and a few of the other composite cermets. During the operation of a SOFC, it is necessary to avoid carburization and sulfidation problems. The present review focuses on the various aspects pertaining to a potential electrode material, the double perovskite, as an anode and cathode in the SOFC. More than 150 SOFCs electrode compositions which had been investigated in the literature have been analyzed. An evaluation has been performed in terms of phase, structure, diffraction pattern, electrical conductivity, and power density. Various methods adopted to determine the quality of electrode component have been provided in detail. This review comprises the literature values to suggest possible direction for future research.
