Abstract

The electrical conductivities of cathode films on a solid oxide fuel cell electrolyte can be determined quantitatively by in situ infrared spectroscopy over a wide range of temperatures and partial oxygen pressures. This method allows measurement of the electrical conductivity of an electrode film on the electrolyte excluding leakage current effects through the substrate.
