摘要: Abstract Anode-supported solid oxide fuel cells (SOFC) based on gadolinia-doped ceria (GDC) are developed in this study. A carbonate co-precipitation method is used to synthesize the nano-sized GDC powders. dense electrolyte thin film supported by a Ni–GDC porous anode fabricated dry-pressing and spin-coating processes, respectively. In comparison with dry pressing, it easy prepare thinner novel method. Cell performance examined using humidified (3% H 2 O) hydrogen as air oxidant temperature range of 500–700 °C. strongly dependent thickness. With anode, 19-μm La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3 –GDC cathode, cell exhibits maximum power densities 130, 253, 386 492 mW cm −2 at 500, 550, 600 650 °C, It also found that low operating about 500 °C, resistance significantly dominated electrode polarization resistance.
