3 - Electronic properties of solids for solid oxide fuel cells (SOFCs)

Abstract

The performance of an oxide used as an electrode or as an interconnect between cells of an SOFC depends critically on the electronic properties of the oxide. However, there are very few reports in the literature that discuss how the electronic properties of an oxide effect the electronically conducting electrodes and interconnect in an SOFC. In this chapter, the electronic properties of oxides are discussed from the perspective of solid-state physics, and the results are applied particularly to electrode and interconnect materials commonly used in SOFCs.
