Pulsed laser deposition (PLD) has been shown to be a promising method to engineer functional interlayers to enhance the cell's performance. In the present study, a bilayer consisting of Sm0.2Ce0.8O2−δ (SDC) barrier layer (BL) and a nanocomposite consisting of SDCLa0.8Sr0.2MnO3−δ (SDC-LSM) employed as a cathode functional layer were deposited by PLD in an anode supported SOFC. The fuel cell showed maximum power density of 0.30 W∙cm−2 at 750 °C. Most importantly, a durability test carried out for 700 h at 750 °C showed a remarkably stable performance of the fuel cell.1453-1462openAccessfuel cellssolid oxide fuel cellslayersthin filmsdepositionlasersArtigo de periódico611110.1149/11106.1453ecst0000-0003-0708-2021https://orcid.org/0000-0003-0708-2021Sem PercentilSem Percentil CiteScore
