Abstract
This paper describes a manometric method for the determination of chemical diffusion coefficients from gas/solid equilibration kinetics for electrode materials of the type (La,Sr)(Mn,Fe,Co)O 3. The equilibration kinetics was monitored by measurements of the p(O 2) changes during a reaction between oxygen and the electrode material involving both oxidation and reduction experiments in the temperature range 773–1123 K. Activation energy of the chemical diffusion measurements at different temperatures was determined during both oxidation and reduction experiments. The chemical diffusion coefficients measured by the present manometric method on La 0.8Sr 0.2MnO 3−δ have been compared with those reported in the literature.
