“…The fuel cell with a nanoscaled SDC buffer layer fabricated by PLD displayed a higher PPD of 2016 mW cm –2 at 700 °C than the cell with the spray-deposited SDC interlayer (1132 mW cm –2 ) . It was also reported that the cell based on the SDC interlayer fabricated by PLD with a thickness of 3 μm showed a higher cell performance than the cell based on the interlayer fabricated by dip-coating with a thickness of 4.5 μm . It suggested that the thickness of the interlayer also showed great influence on the cell performance.…”

“…129 The cell with the SDC buffer layer fabricated by PLD delivered a high PPD of 2016 mW cm −2 at 700 °C, outperforming the analogous SOFCs with spray-deposited buffer layer and without the buffer layer and (1132 and 60 mW cm −2 , respectively), which was attributed to the inhibition of the detrimental phase reaction between YSZ and BSCF, the smaller thickness comparing with the spray-deposited SDC buffer layer as well as an improved charge transfer process. 129 The effects of deposition methods on the performance of SOFCs with SSC cathode and SDC interlayer were investigated by Qian et al 130 A thin and pure-phase SDC layer was fabricated by PLD at a low substrate temperature of 600 °C In addition, the cell with SDC interlayer prepared by PLD delivered a much superior PPD of 0.714 W cm −2 at 700 °C to those of the cells with the dip-coated interlayer (0.513 W cm −2 ) and without the interlayer (0.366 W cm −2 ) at 700 °C.…”

Solid oxide fuel cells (SOFCs) as one of the clean electrochemical energy conversion devices have acquired increasing attention recently due to the high efficiency, low emission, and excellent fuel flexibility. Nevertheless, the practical application of SOFCs is hindered by poor stability and high cost. Thus, lowering the operating temperatures is critical to increase the lifetime and reduce the cost of SOFCs. However, the electrolyte and electrode materials used in high-temperature SOFCs suffer from insufficient ionic conductivity and poor electrocatalytic activity at lower operating temperatures, respectively. Nanomaterials and relevant nanotechnologies have great potential to enhance the performance of SOFCs operated at lower temperatures because of the enlarged surface area, distinct surface, and interface properties. Among various nanotechnologies, pulsed laser deposition (PLD) has been widely employed in SOFCs to reduce the operating temperature. Herein, we present an in-time review about the PLD-involved fabrication of key components in intermediate-temperature (IT) SOFCs in terms of cathodes, electrolytes, anodes, and interlayers. The superiority of the PLD technique to other traditional fabrication methods is emphasized, and design strategies for the key components in IT-SOFCs are presented and discussed. We also point out the trends, current challenges, and future directions that exist in this dynamic field. This review will inspire substantial interests from various disciplines and provide some valuable guidance for future development of PLD-involved energy storage and conversion devices.

“…Therefore, developing new electrolyte materials with better thermochemical stability and improved electrochemical performance is essential. Doping zirconia with various cations such as Ca 2+ , Mg 2+ , Sc 3+ , Y 3+ , and some other rare earth metal cations such as Yb 3+ , Gd 3+ , Nd 3+ , and Sm 3+ result in the formation of stabilized zirconia with fcc cubic structure that offers excellent ionic conductivity, particularly above 1000 • C [15]. Introducing certain amounts of the tetragonal gadolinia (Gd 2 O 3 ) into the zirconia structure can create a stable gadolinium zirconate with various cubic, tetragonal, and monoclinic phases offering high ionic conductivity and thermal stability [16,17].…”

Zirconia-based composites with high thermochemical stability and electrochemical activity are the most promising solid electrolytes for manufacturing solid oxide fuel cells (SOFCs). In the present work, nanocrystalline composite powders of gadolinium-doped zirconia (GDZ: Gd2xZr2(1−x)O4−x) with various doping fractions (0.01 ≤ x ≤ 0.16) were synthesized by the Pechini method and applied for the fabrication of several electrolyte pellets to evaluate their physicochemical properties, sinterability, and conductivity. The X-ray diffraction (XRD) patterns and the thermogravimetry/differential thermal analysis (TGA/DTA) of the synthesized powders confirmed the successful formation of nanocrystalline GDZ in the tetragonal phase with complete substitution of gadolinium phase into the zirconia (ZrO2) lattice. The synthesized gadolinium zirconate powders were then shaped into pellet forms using the tape casting method, followed by sintering at 1300 °C (for 2.5 h). The microstructural analysis of the electrolyte pellets showed suitable grain boundary welding at the surface with an acceptable grain growth at the bulk of the T-phase GDZ samples. The impedance measurements indicated that the T-phase GDZ-8 could provide a comparably higher ionic conductivity (with 7.23 × 10−2 S/cm in the air at 800 °C) than the other dopant fractions. The results of this work can help better understand the characteristics and electrochemical performance of the T-phase gadolinium zirconate as a potential electrolyte for the fabrication of SOFCs.

The aim of this study is to specify an optimal method for coating LSM layer on a YSZ substrate. Initially the prepared powders were validated by X-Ray Diffraction (XRD) technique. A mixture of NiO-YSZ (50:50 wt%) powders were created by mechanical milling method; then the mix was prepressed in a disk shape die as the base substrate; after that, YSZ powder was added on the substrate and they were pressed and sintered at 1450°C for 3 hours. Three different methods including dip coating, spraying, and brush painting using various concentrations of LSM suspensions, were applied on the obtained substrate. Then, LSM coated disks were sintered at 1250°C for 2 hours. The coating surface and the cross section of the as-sintered disks which were investigated and scanned by an electron microscope (SEM), illustrated a uniform coating in dip-coated samples; also, another advantage of this method was the negligible agglomeration of the LSM layer. Moreover, the linear EDS elemental analysis from the surface of the layer -which is coating the substrate-indicated the desired results for the coating which was fabricated by the dip coating method.
