| Research Abstract |
The electrical performances of cathode-supported SOFCs, fabricated in this study by a dual drying pressing method, reached to a high level in comparison with those from corresponding references. The degradation mechanism of Ni-based anode at low concentrations of CH_4 and H_2 was studied. The results show: (1)Degradation is due to the re-oxidation of Ni at high water vapor concentration; (2)Degraded anode could get recovered by burning it in O_2 followed by reduction in H_2, (3)The corresponding mechanism of the recovery was preliminary proposed. This study provides a new technique to evaluate the degradation phenomenon in methane fueled SOFCs using a simple method.
