The improvement of barium-containing anode for ceria-based electrolyte with electron-blocking layer
Source abstract
Abstract
Abstract An original approach aiming at the improvement of barium-containing anode in the reduction of partial internal electronic short circuit for ceria-based electrolyte in intermediate temperature solid oxide fuel cells (IT-SOFCs) was proposed in this research. The improved cells employed by mixed proton-oxide ion-electron conducting composite anodes show efficiently enhanced properties, especially in the effective increase of power densities. The electron-blocking layer can be maintained with a suitable proportion of Gd 0.1 Ce 0.9 O 2-δ (GDC) below 20 mol% at anodes. Furthermore, a mechanism for barium diffusion and ionic conduction behavior in barium-containing anodes of the improved cells was proposed.
