Titanium (Ti)-based oxide anodes are excellent anode materials which have been applied widely in electrochemical fields all over the world. Adding intermediate layers in Ti-based oxide anodes can improve the conductivity, lengthen the lifetime and strengthen the stability between Ti base and metal oxides active layers of electrodes. This article reviews the research progress of intermediate layers in Ti-based oxide anodes. At the same time, current problems existed in the field of Ti-based oxide anodes are pointed out and future development trend in oxide electrode with intermediate layers is prospected.

A novel composite electrolyte SDC-(Li/Na)2SO4 was prepared for intermediate temperature solid oxide fuel cells (ITSOFC). The phase structure and cross-sectional morphology were examined by XRD and SEM, respectively, and the ionic conductivity was investigated by AC impedance in a temperature range of 400 oC ~ 700 oC in air. It was found that the composite electrolyte was composed of two phases: crystal SDC and amorphous (Li/Na)2SO4. The conductivity of the composite electrolyte was significantly larger than that of SDC at intermediate temperatures (550 oC ~ 700 oC) and increased …
