Conductivity of MCFC Cathode Material-Lithium Ferrite Oxide

The conductivity performance of lithium ferrite oxide for molten carbonate fuel cells was investigated. The results showed that the conductivity of lithium ferrite oxide can be improved by making Li₂CO₃ excessive slightly in the process of preparing lithium ferrite oxide. At the same temperature, the conductivity of lithium ferrite oxide increases with the increasing of Li:Fe values. However, at the same Li:Fe value, the conductivity of lithium ferrite oxide increases exponentially with the increasing of temperature. It was shown from the SEM analysis that the electrode surface micrographics of lithium ferrite oxide with various Li:Fe values are different.
