Anode‐supported micro‐tubular SOFCs based on a proton and oxide ion mixed conductor electrolyte, BaZr0.1Ce0.7Y0.1Yb0.1O3−δ (BZCYYb), have been successfully fabricated via phase‐inversion process. Typical micro‐tubular cell with the configuration of Ni‐BZCYYb|BZCYYb|La0.6Sr0.4Co0.2Fe0.8O3–δ, consists of anode support, electrolyte and cathode with thicknesses of 200, 12, and 10 μm, respectively. The cells show excellent electrochemical performance with the peak power densities of 1.040, 0.902, 0.721, and 0.590 W cm−2 at 750, 700, 650, and 600 °C, respectively, with humidified (3 vol.% H2O) hydrogen as fuel and ambient air as oxidant. The AC impedance spectroscopy result shows low concentration polarization values of 0.016–0.021 Ω cm2 at 750–600 °C. Further, significant performance enhancement is observed during long‐term stability test at 600 and 750 °C under constant voltage of 0.5 and 0.7 V over 120 h, respectively, indicating excellent stability of BZCYYb under fuel cell operating condition. The high performance is attributed to high‐quality cell, validated by the dense, crack‐free BZCYYb electrolyte film supported by the anode with micro sponge‐like pores.

“…In the last decades, solvothermal synthesis techniques have been employed in the synthesis of SOFC materials, from hydrothermal (in the case of solvent water), to microwave-assisted, and CHFS. [136][137][138][139][140][141][142][143][144] However, very limited research studies have been published on the utilization of CHFS to fabricate in situ inkjet inks, most likely due to the novelty involved. To the best of our knowledge, no more than three such publications have been reported so far.…”

With energy demands increasing globally, [1] the prevention of an upcoming energy crisis has been established as a crucial challenge of our era. [2] While fossil fuels still constitute the primary Solid oxide fuel cells (SOFCs) are high temperature galvanic devices able to electrochemically convert chemical energy of fuels to electrical energy at remarkably high efficiencies. However, several challenges, associated with the complexity, scalability, and cost of the current fabrication processes, remain to be resolved for their large-scale deployment. Additive Manufacturing (AM) methods are proposed to address such fabrication-related issues, with Inkjet Printing (IJP) being one of the most promising. In this review, the use of IJP is examined as a potential AM method to deposit electrode and electrolyte thin films for SOFCs. The most important aspects of IJP for SOFCs fabrication processes, including ink formulation of active materials, inkjet deposition, printing optimization, and characterization of inkjet-printed thin films, are described in detail. Additionally, the effect on electrochemical performance of inkjet-printed SOFCs highlights the overall potential of this fabrication technique. Challenges and opportunities for the future development of the topic are also discussed.

The present research demonstrates the synthesis and characterization of LaMnO3 perovskite powders using the sol-gel technique for dye-sensitive solar cell applications. With this respect, transparent solutions were prepared from La and Mn based precursors, distilled water and citric acid monohydrate. Ammonium hydroxide was incorporated into the La-Mn solution in order to neutralize/precipitate at 24oC for 1 hour in the air. The solution was allowed to evaporate on a hot plate device at 90 °C in the air. The obtained solutions were dried at 90 oC for 24 hours to form a xerogel structure, dried at 200 oC for 2 hours and consequently annealed at 500 and 850 oC for 2 hours in the air. Thermal, structural, microstructural, optical and magnetic properties of the powders were characterized through differential thermal analysis-thermogravimetry (DTA-TG), Fourier transform infrared (FTIR), X-ray diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS), scanning electron microscopy (SEM), Malvern zeta sizer (PSD), UV-vis spectrometer and vibrating sample magnetometer (VSM). The obtained results indicate promise, especially the low band range, that LaMnO3 powders can be used in dye-sensitized solar cells and can positively affect performance and efficiency.
