“…With (LaSr)(CoFe)O 3 being La 0.6 Sr 0. 4 [7]. The addition of 50 vol.-% GDC to (LaSr)(CoFe)O 3 has resulted in an increase in the ionic conductivity with a factor of about 10 compared to that of the (LaSr)(CoFe)O 3 cathode [21].…”

A solid oxide fuel cell (SOFC) unit is constructed with Ni‐Ce0.9Gd0.1O2 – δ (GDC) as the anode, yttria‐stabilised zirconia (YSZ) as the electrolyte and Pt, Ag or Cu‐added La0.58Sr0.4Co0.2Fe0.8O3 – δ (LSCF)–GDC as the cathode. The current–voltage measurements are performed at 800 °C. Cu addition leads to best SOFC performance. LSCF–GDC–Cu is better than LSCF–GDC and much better than GDC as the material of the cathode interlayer. Cu content of 2 wt.‐% leads to best SOFC performance. A cathode functional layer calcined at 800 °C is better than that calcined at higher temperature. Metal addition increases the O2 dissociation reactivity but results in an interfacial resistance for O transfer. A balance between the rates of O2 dissociation and interfacial O transfer is needed for best SOFC performance.

“…The self-healing behavior exhibited in the Ag-LSCF and Ag-LSM composites could be attributed to the sintering activity of the respective ceramics, most likely assisted by Ag. It has been widely reported that LSCF is sinterable at temperatures as low as 700°C, which explains why the cells with the Ag-LSCF contact materials showed a gradually decreasing ASR once the cells were returned to their operating temperature of 800°C [12][13][14]. LSM, on the other hand, requires sintering temperatures in excess of 1100°C to achieve adequate densification and electrical conductivity [15][16][17].…”

“…Perovskite-type oxide materials have attracted many attentions as ITSOFCs anodes due to their mixed-conducting characteristics and higher ionconductivity in the intermediate temperature range [11][12][13]. Among those perovskite-type oxides, SrTiO 3 shows great potential as an anode material and receives considerable attentions.…”

A novel anode material for intermediate temperature solid oxide fuel cells with a composite of La x Sr 1-x TiO 3 has been synthesized by a sol-gel auto-combustion method. X-ray diffraction (XRD) shows that La x Sr 1-x TiO 3 has good chemical compatibility with Gd 0.2 Ce 0.8 O 1.9 electrolyte. The thermal expansion coefficient (TEC) of the as-prepared anode material is similar to that of Gd 0.2 Ce 0.8 O 1.9 . The electric conductivity measurements show that the conductivity of La x Sr 1-x TiO 3 increases with the increasing of lanthanum contents and reached a maximal value at x=0.3. At 800 o C, the electrical conductivity of La 0.3 Sr 0.7 TiO 3 is 184S·cm -1 .
