Abstract
A highly-conducting ceramic material, identified as stable in molten carbonate electrolyte, has been fabricated by partial sintering of the powder into porous gas-diffusion electrodes. These have been tested with commercial molten carbonate electrolyte ‘tiles’, to compare performance with that of state-of-the-art NiO cathodes. Although the fabrication technique was quite simple, the resultant La0.8Sr0.2CoO3 electrodes showed kinetic performance equivalent to the NiO. This, or other perovskite or spinel-structure ceramic shown to be totally system compatible in long-term tests, can be formed into effective electrodes to replace NiO.
