dc.description.abstract | Using the powder-ball generation phenomenon in the electrostatic slurry spray deposition (ESSD), the embossing structures are introduced on the gadolinium-doped ceria (GDC) electrolyte to expand the cathode-electrolyte interface and three phase boundary. To verify the influence of embossing structure, the half and single cells composed of the GDC electrolyte and La0.6Sr0.4Co0.2Fe0.8O3-delta (LSCF) cathode are fabricated by the ESSD. The half cell with embossing deposited for 30 s (8.6% of electrolyte surface coverage) shows the lowest cathode polarization resistance, which is lower than that of the half cell without embossing by 62.3%. For the single cells, the maximum power densities are estimated to 0.171 W cm(-2) and 1.06 W cm(-2) for the cell without embossing and 0.232 W cm(-2) and 1.19 W cm(-2) for the cell with embossing at 550 degrees C and 750 degrees C, respectively. Additionally, the open circuit voltage (OCV) is increased by 2-5% at 550-750 degrees C range. According to the half and single cell results, it may be concluded that the maximum power densities and OCVs of the single cells with embossing increase simultaneously and this improvement is more effective in lower temperature range.
