Abstract
A bi-continuous porous cathode consisting of nano-particles of strontium substituted lanthanum cobaltite (LSC) covering the surface of a Ce0.9Gd0.1O1.95 (CGO10) backbone has been produced. The polarization resistance (R (P)) of this cathode was measured to similar to 35 m Omega cm(2) at 650 A degrees C.
The area-specific resistance at 650 A degrees C (ASR) when applied onto an anode supported cell (ASC) was found to increase from 540 to 730 m Omega cm(2) when subjected to a thermal cycle to 850 A degrees C. This effect was attributed to particles coarsening but also to a reaction with the electrolyte.
The results imply that a CGO10 barrier is required for this type of nano-structured cathode.
