WebGd-doped Ceria (GDC) barrier layers are widely used in solid oxide electrolysis cells to prevent reactions between the Y-stabilized Zirconia (YSZ) electrolyte and oxygen electrode. In some cases, electrolysis operation causes fracture near the GDC/YSZ interface. Here, we explain this effect using a numerical calculation, showing that a peak oxygen pressure is … Websintered GDC barrier layers. This is confirmed by the REM images which were obtained from those layers. At first, attention is drawn to the barrier layers prepared from the sonicated sample (i.e. without milling and centrifugation). Figures 4 and 5 show profiles and surfaces of those layers for
Web2 days ago · Moreover, a GDC barrier layer-free configuration is adopted for the anode-supported SOFCs (Fig. 1 b). The GDC cation diffusion barrier layer is used to keep the SOFC cathode and electrolyte layers from interacting during sintering and cell operation. However, the fabrication of the GDC layer itself is a challenging process due to the high ...
