Anode-supported tubular SOFC at low temperature using Ni, Fe, GDC, and YSZ based anode support
- Chemical Sciences and Engineering Division
NiO-GDC, NiO-YSZ, NiO-Fe2O3-GDC, NiO-Fe2O3-YSZ anode tube supported tubular fuel cells was fabricated at the co-sintering temperature from 1250 C to 1400 C to investigate how the co-sintering temperature affect the open-circuit voltage. To focus on the changing of anode tube, all the tubular fuel cells support a ScSZ electrolyte layer and a LSCF cathode layer. The microstructure of the electrolyte layer sintered under 1300 C included pores inside it, and the densification of the electrolyte completed at the sintering temperatures above 1300 C. Furthermore, the shrinkage both in length and in diameter of a tubular fuel cell reaches as much as 20% at co-sintering temperature of 1400 C. The densification of ScSZ electrolyte layer and shrinkage of anode tube will result in the changing of open-circuit voltage of fuel cell from 1.0 V to 1.1 V.
