摘要

The effects of co-sintering temperature on anode microstructure, electrolyte film microstructure, and final cell performance of tubular solid oxide fuel cells (SOFCs) were fully studied. The co-sintering of the NiO/YSZ anode-YSZ electrolyte double layers at temperature ranging from 1350 to 1400 ℃ for 5 h was carried out. Porosity and electrical conductivity were measured to examine the anodes microstructure, and the electrolyte films microstructure were characterized by scanning electronic microscope (SEM). A higher open current voltage (OCV) value of 0.99 V was achieved by co-sintering the cell at 1400 ℃ indicating denser electrolyte film, while the maximum power density of the cell co-sintered at 1380 ℃ was achieved with 322 mW cm~(-2) at 800 ℃, which was higher than that (241.3 mW cm~(-2)) of the cell co-sintered at 1400 ℃ because of better anode microstructure.
