![عکس صفحه اول مقاله: Effect of anode microstructure on the performance of micro tubular SOFCs Effect of anode microstructure on the performance of micro tubular SOFCs](/preview/png/1297874.png)
Here we report the effect of anode microstructure on the SOFC performance using two types of micro tubular SOFCs, 0.8 and 1.6mm in diameter with different anode microstructure (Cells A and B). The cells consisted of NiO-Gd doped ceria (GDC) as an anode (support tube), GDC as an electrolyte and (La, Sr)(Fe, Co)O3 (LSCF)-GDC as a cathode. The anode tube for Cell A was prepared using NiO (dg~ 5µm) and GDC (dg~ 0.2µm) powders without using a pore former, while the anode tube for Cell B was prepared using NiO (dg~ 0.5µm)and GDC(dg~ 0.2µm) powders using a pore former. The peak power density of these cells were shown to be 203, 400 and 857mW cm− 2 for Cell A and 273, 628 and 1017mW cm− 2 for Cell B, respectively at 450, 500, and 550°C operating temperature. Both cells showed outstanding performance, and furthermore the anode microstructure of Cell B was shown to be more optimized for better cell performance.
