Optimization on technical parameters for fabrication of SDC film by screen-printing used as electrolyte in IT-SOFC

Preparation and performance of solid oxide fuel cells with YSZ/SDC bilayer electrolyte

“…DPC (doped-CeO 2 ), such as Sm-doped CeO 2 (SDC), Gd-doped CeO 2 (GDC) and Y-doped CeO 2 (YDC) has been proposed as a potential candidate for intermediate temperature-SOFC (IT-SOFC) electrolyte which works at operating temperature range 600-800 1C, due to its higher conductivity and lower conduction activation energy compared to YSZ (Y 2 O 3 -stabilized ZrO 2 ) [1][2][3][4][5][6][7][8][9][10][11][12][13]. However, DPC is an ion-and-electron mixed conductor in reduction atmosphere.…”

“…The reduction of ceria from Ce 4 þ to Ce 3 þ will give rise to electronic conduction which causes a cell voltage and fuel efficiency loss due to internal shorting [14]. In general, a single SOFC based on doped ceria electrolyte showed an open-circuit voltage (OCV) of $ 0.8 V [6,[15][16][17]. In order to overcome the OCV loss, one of the proposed approaches is to fabricate YSZ layer to block the electron conducting between the DPC electrolyte and electrode to form YSZ/DPC bilayer electrolyte structure.…”

“…For example, Martinez-Amesti et al reported the results on interdiffusion at the YSZ/SDC interface below 1300 1C [24]. Generally, for getting dense SDC film, the temperature for sintering should be 1400 1C or above [6,25], and more detailed investigation on the interdiffusion near the n interface at this sintering temperature (1400 1C) should be done. However, to our knowledge, there is no systematic report on the ion interdiffusion at the YSZ/SDC interface at 1400 1C.…”

Thermal stability of atmospheric plasma sprayed (Ni, Cu, Co)–YSZ and Ni–Cu–Co–YSZ anodes cermets for SOFC application

“…These coatings were elaborated by atmospheric plasma spraying (APS) technique. Many processes were developed for SOFCs anode cermets achievement, among them, the conventional ceramic sintering, a low cost solid-state method and an easy one to realize [15][16][17][18][19].…”

Synthesis and characterization of spray deposited PdO–NiO–SDC composite anode material for potential application in IT-SOFC

“…Another material, NiO-samaria doped ceria (SDC), has been used as anodes for intermediate temperature solid oxide fuel cells [19][20][21][22][23]. In the present investigation SDC is added to Ni.…”
