Investigation of LSM–ScSZ composite cathodes for anode-supported solid oxide fuel cells

La0.4Ce0.6O1.8–La0.8Sr0.2MnO3–8mol% yttria-stabilized zirconia composite cathode for anode-supported solid oxide fuel cells

“…In our previous work, we reported that using ScSZ as an ion conductor other than YSZ in the composite cathode reduced the R p , especially in the low temperature range [21]. It was indicated that the ceria doped in the ScSZ electrolyte also contributed to the oxygen reduction processes.…”

Development of LSM-based cathodes for solid oxide fuel cells based on YSZ films

“…The MPDs are 90, 110 and 37% higher than those with the air oxidant for Cell-1, Cell-2 and Cell-3, respectively. The MPD of Cell-2 is better than the high cell performance (2.24 W cm −2 at 800 • C) with LSM/Sc 2 O 3 -stabilized ZrO 2 co-doped CeO 2 (ScSZ) cathode [19]. The dramatic promotion in the cell performance, typically Cell-2 well implies that gas conditions at the cathode side as well as the cathode microstructure and porosity play a significant role in determining the cell performance.…”

“…Also, the higher ionic conductivity and higher oxygen surface exchange coefficient of SDC than those of YSZ are suggested as the two main factors aiding electrode processes [9]. Furthermore, the special redox properties of Ce 4+ and Ce 3+ can facilitate the surface diffusion and charge transfer processes [19]. These are the reasons why the Cell-3 performance is higher than Cell-2.…”

Dynamic evaluation of low-temperature metal-supported solid oxide fuel cell oriented to auxiliary power units

“…Over the past two decades, technical developments have focused on both the reduction of the operating temperature and the development of advanced materials to improve the performance and the durability of the cell [1][2][3]. These efforts are mainly oriented towards stationary applications like centralized power stations or distributed power suppliers.…”
