摘要

The developed metal-supported solid oxide fuel cell consisting of a Ni-MoFe metal substrate as cell support, a double layer formed of La_(0.75)Sr_(0.25)Cr_(0.5)Mn_(0.5)O_(3-δ) (LSCM) and nanostructured Ce_(0.55)La_(0.45)O_(2-δ) -Ni (LDC-Ni) as anode, an LDC as anode interlayer, an La_(0.8)Sr_(0.2)Ga_(0.8)Mg_(0.2)O_(3-δ) (LSGM) as electrolyte, a Sm_(0.15)Ce_(0.85)O_(3-δ) (SDC) as barrier layer and a Sm_(0.5)Sr_(0.5)CoO_(3-δ)(SSC) as cathode is prepared using an atmospheric plasma spraying (APS) coating process. The measured maximum output power densities are 788, 666,497 and 317 mW cm~(-2) at 750, 700, 650 and 600°C respectively. In the 280 h durability test at 400 mA cm"2 constant current density and 650°C , the measured voltages starting from 822 mV and ending at 775 mV show a degradation rate of about 20% kh~(-1), but after the tested cell is heat treated at the 800°C and OCV condition for 4 h, the measured voltage at 400 mA cm~(-2)constant current density load and 650°C is back to 825 mV that is greater than the initial cell voltage of 822 mV. All of the I-V curves, I-P curves, AC impedances and the voltages measured before and after the durability test show that the tested cell is recovered and demonstrate that the heat treated process around 810°C and at OCV condition for 4 h is effective to recover the performance of the prepared metal supported cell. The phenomenon of the recoverable cell performance is also observed in the experimental data of another prepared metal supported cell heated in the same furnace.
