“…at the LSM/YSZ interface, we also prepared a bi-layered structure of LSM/YSZ sintering to 1300℃, as shown in Table II. Yang et al (11) observed that when YSZ/LSM cofired at 1400℃ for 2, 12, and 52 hrs, many impurities phases such as La 2 Zr 2 O 7 (LZ), SrZrO 3 (SZ), ZrO 2 were formed. Figure 5 provides the XRD pattern for the YSZ (nano) thin film and the LSM substrate when sintered at 1300℃.…”

“…This value is better than those of cells without 3DOM anode structure. For example, Besra et al reported the maximum power density of 144 mW cm -2 for LSM-YSZ / YSZ / Ni-YSZ cell at 700°C (12). Their cell had a dense YSZ electrolyte with about 10 µm thickness, but the anode structure was not porous.…”

Ni-YSZ anode with three-dimensionally ordered macroporous (3DOM) structure was applied to solid oxide fuel cell, in order to demonstrate high potential of 3DOM structure for electrodes of intermediate temperature solid oxide fuel cells (IT-SOFCs). Polystyrene beads with particle size of 2.5 µm or 1.4 µm were used as the template for 3DOM Ni-YSZ. The cell with LSM-YSZ / YSZ / 3DOM Ni-YSZ configuration showed better performance than that of the conventional cell with random-structured Ni-YSZ. The polarization resistance of Ni-YSZ anode was further reduced due to 3DOM structure with the smaller pores that provided large electrochemical interface. Consequently, 374 mW cm -2 and 119 mW cm -2 were obtained as the maximum power densities at 700°C and 600°C, respectively.

“…Figure 4 shows the EIS response and its equivalent circuit (LR b (R 1 Q 1 )(R 2 Q 2 )) of the single cell at different temperature, and all the spectra of the single cell were similar in shape. The intercept with the real axis at high frequencies represents the resistances of the electrolyte (R b ) 33 as shown in left inset, whereas the difference between the highfrequency and low-frequency intercepts with the real axis represents the sum of the electrode polarization resistances of the cell (R p ). The polarization resistance includes the resistance to the electrochemical processes such as charge transfer and mass transfer, which is the sum of R 1 and R 2 .…”

Yttria-stabled zirconia (YSZ) electrolyte film was prepared on NiO/YSZ anode substrate by a slurry dip-coating technique for intermediate temperature solid oxide fuel cells (IT-SOFCs). The pre-sintering temperature of the anode substrate is crucial to the densification of the electrolyte films, and an optimal temperature of 1000 o C was determined. SEM tests indicated that homogeneous and dense electrolyte film with a thickness of 24 µm could be obtained by twice dip-coating, with good adhesion to the anode substrate. A cell assembled with the prepared YSZ electrolyte films presents an open circuit voltage (OCV) of 1.14 V and a power density of 0.50 W•cm -2 operated at 800 oC. The slurry dipcoating technique was also applied to fabricate YSZ films for large size IT-SOFCs, and the maximum power density is 146 mW•cm -2 . This result indicates that the slurry dip-coating technique for preparation of YSZ electrolyte films has potential application in fabricating SOFC stacks.
