“…A previous study synthesized Ni/10Sc1CeSZ anode using GNP assisted by a uniform microwave heating technique. The results showed improvements in the performance due to the improvement in the morphology of the cermet powder 166 ; such improvement is a result of the uniform heating by the microwave energy.…”

The primary components of SOFCs are the anode, cathode, and the electrolyte. Anode is critical in achieving the effective electrochemical oxidation of fuel; thus, its performance can be improved using homogenous powder synthesized through an appropriate method. Various synthesis methods, including solidstate reaction and wet chemical methods have been used to synthesize anode materials. However, each technique has several advantages and disadvantages.Given that anode is a porous electrode, few criteria, such as high conductivity, tolerance towards carbon deposition, chemical stability, and thermal stability, must be fulfilled. Researchers also modified the existing synthesis method to improve the performance of the anode. In addition, various anode fabrication techniques including physical and colloidal deposition techniques are briefly discussed to understand their effect on the performance of the deposited layers.The aim of this review is to discuss the various anode synthesis and deposition techniques and their influence on the properties and performance of SOFCs.

In this study, the perovskite‐type oxide LaFeO3 is treated by electroless Ni deposition with different reaction time and the electrochemical properties of the resulting material are investigated as the anode for MH‐Ni batteries. XRD, SEM, and TEM measurements reveal a uniform deposition of crystalline nickel on the oxide surface and a clear increase in the amount of Ni coating with the deposition time. The electrochemical analysis shows that the electroless deposition can significantly improve the maximum discharge capacity of the battery. Furthermore, the coated electrodes exhibit excellent activation performance and superior cyclic stability. With the increase in the reaction temperature, improvements in the discharge ability, exchange current density, and diffusing coefficient of hydrogen are also observed.

“…Conductivity was measured via the four-point van der Pauw method described in. 26,27 Button-shaped symmetrical cells were placed onto a homemade sample holder equipped with platinum wires attached through four probes. The electrical conductivity of the cathodes was recorded starting from the operating temperature of 700 C up to 500 C. The electrical conductivity and activation energy of each cathode were then calculated.…”

LiCoO 2-based materials are well-known cathode materials used in lithium ion batteries. Moreover, these materials are currently utilized in low-temperature proton-conducting solid oxide fuel cells (SOFCs). Various dopants, such as Mn, Sr, and Zn, are introduced into LiCo 2-based materials to improve their properties and performance for proton-conducting SOFC applications. In this regard, Mn-, Sr-, and Zn-doped LiCoO 2 and LiCo 0.6 X 0.4 O 2 (X = Mn, Sr, or Zn) powders are synthesized via the glycine-nitrate combustion method. Their properties are characterized using different techniques. The precursor cathode powder is dried at 100 C and subjected to thermogravimetric analysis (TGA). The phase formation and morphology of calcined LiCo 0.6 Mn 0.4 O 2 (LCMO), LiCo 0.6 Sr 0.4 O 2 (LCSO), and LiCo 0.6 Zn 0.4 O 2 (LCZO) powders at 600 C to 700 C are examined via X-ray diffraction. At 600 C, both calcined LCSO and LCZO powders show few secondary phases, but these phases greatly decrease as calcination temperature increases to 700 C. By contrast, calcined LCMO powders exhibit a single phase structure at both calcination temperatures of 600 C and 700 C. The measured crystallite sizes of LCMO, LCSO, and LCZO powders are 23.32 ± 0.20, 21.08 ± 0.72, and 21.24 ± 0.32 nm, respectively. TEM images indicate that the particles in LCMO and LCZO powders highly agglomerate compared with those in LCZO powders. This result confirms that LCSO cathodes have the highest electrical conductivity (356.66 S cm −1) and the lowest area specific resistance (0.29 Ω cm 2 in humidified [3%] air) at 700 C. In conclusion, LCSO materials are the best cathodes with high potential for protonconducting SOFC applications.
