Studies on spray deposited NiO–SDC composite films for solid oxide fuel cells

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

“…Activation energy was found to be 0.24 eV which is comparable to the earlier reported values for NiO-SDC [20] and lower than that reported for doped ceria [33,43,36].…”

“…A.C. conductivity is found to be 3.9 × 10 −1 ( cm) −1 at 350 • C. The conductivity value is higher than that reported by others for doped ceria anodes [20,43]. It has been reported that a microcrystalline material fares far better in terms of ionic conductivity than that the nano-crystalline material [46].…”

“…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.…”

Structural, morphological and electrical properties of spray deposited nano-crystalline CeO2 thin films

“…The highest intensity X-ray diffraction (1 1 1) peak lying at about 2Â = 28 • has been further analyzed to yield the crystallite size of the ceria material by using the Scherrer's formula [34]:…”

Nanostructured and Nonsymmetrical NiO–SDC/SDC Composite Anode Performance via a Microwave-Assisted Route for Intermediate-Temperature Solid Oxide Fuel Cells

“…[29,30]. As shown in Figure 4, a comparison of the Nyquist plots shows that the polarization resistance of high pressure pellets is moderately higher than those of low pressure pellets because of porosity; the effective working area of all samples in this study is 1.32 cm 2 [31].…”
