Fabrication of a large area cathode-supported thin electrolyte film for solid oxide fuel cells via tape casting and co-sintering techniques

Fabrication and characterization of Ni-SSZ gradient anodes/SSZ electrolyte for anode-supported SOFCs by tape casting and co-sintering technique

“…Therefore, governing the cosintering behavior by the heat treatment was an effective method [32,33]. As shown in Fig.…”

Effect of Ag-(La0.8Sr0.2)0.95MnO3 current-collecting layer on the stability of anode-supported solid oxide fuel cell

“…Generally, R o increases with decreasing temperature. But here the R o value at 750 • C is smaller than that at 800 • C. The difference between the high frequency and low frequency intercepts represents the electrode polarization resistance (R p ) [5]. R p is 0.42 cm 2 at 800 • C, and we cannot get exact R p values at 750 and 700 • C due to the instability of the cell.…”

“…corresponds to the total resistance of the cell. The high frequency intercept represents the ohmic resistance (R o ), involving ionic resistance of the electrolyte, electronic resistance of the electrodes, and some contact resistance associated with interfaces [5]. The R o values are 0.10, 0.076, and 0.095 cm 2 at 800, 750 and 700 • C, respectively.…”

“…NiO-Zr 1−x Y x O 2 (YSZ) and NiO-Zr 1−x Sc x O 2 (SSZ) are currently the most common anode materials for SOFC applications [4,5]. The anode side does not need a current-collecting layer because metal Ni is an excellent electronic conductor.…”

“…The anode side does not need a current-collecting layer because metal Ni is an excellent electronic conductor. La x Sr 1−x MnO 3 (LSM)-YSZ and LSM-SSZ are currently the most common cathode materials [5,6]. A current-collecting layer is often added to surface of cathode due to the poor electronic conductivity at the cathode side.…”
