“…110 In addition to gasses or ceramics, this method is widely used in synthesizing organics and biomaterials. 15 The word "sol-gel" came from the process or transition from liquid to solid (di-or multi-phasic gel). This process involves hydrolysis and condensation or dispersal of metal alkoxides, in which the organic and inorganic salts of metal species are mixed.…”

“…SOFCs are well-known for its high-quality exhaust heat for cogeneration in high temperatures (600-1000 C). 15 Despite the advantages and high efficiency of high-temperature SOFCs, the challenges for material compatibility are costly. 16 Therefore, intermediatetemperature (500-750 C) 17 and low-temperature SOFCs (300-500 C) 18 are considered to reduce the overall cell operation cost.…”

“…The synthesis method affects the microstructure, porosity, particle size distribution, particle shape, and TPB of the anode. 27 Some of the approaches that are used to synthesize anode materials including ball milling, [28][29][30][31][32] solid-state reaction (SSR) method, [33][34][35] template-based synthesis method, [36][37][38] and wet chemical methods (WCMs), such as sol-gel, 15,[39][40][41][42][43][44][45] co-precipitation, [46][47][48][49] hydrothermal and solvothermal methods, 48,50,51 and combustion method. [52][53][54][55][56][57][58] Various deposition methods were also discussed and categorized in several groups including physical deposition, [59][60][61][62][63][64][65][66] chemical deposition, [67][68][69] and colloidal deposition.…”

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.

“…The processing method of the electrode powders determines the particle size. An increase in particle size leads to a decreasing in surface area of the electrode, which then yields higher resistance and poor conductivity in the component [74], [75]. All the factors mentioned here need to be considered before producing the copper doped electrodes.…”

The new coronavirus (COVID-19) has started spreading all over the world. Every infected is fighting to recover a little and every health worker is fighting to save a single life in this pandemic. There is no place for patients to stay in the hospital, health workers are given all possible services to save their lives. In this situation, uninterrupted power system is needed, which can be supplied by solid oxide fuel cells (SOFCs). Therefore, solid oxide fuel cells (SOFCs) are becoming attractive day by day with competing environmentally friendly energy sources due to high energy efficiency, low emission rate and comparatively low operating cost. The purpose of this work is to investigate how copper-doped perovskite electrode materials impact the performance of solid oxide fuel cells (SOFCs) to overcome such crucial times successfully. Different synthesis process of Cu-based electrodes and analyzing electrochemical properties were investigated in this work. The evaluation was performed in terms of synthesis process, sintering temperature, lattice type and parameters, electrical conductivity, thermal expansion coefficients (TEC), polarization resistance, activation energy, and power density. In order to provide additional energy during this pandemic COVID-19, low-cost, highly performed, and durable materials are needed to make SOFC.

“…However, high temperatures may sometimes lead to high polarization resistances, as shown by Barfod et al 14 , and reducing the polarization resistance is also an active area of research. Research efforts over the years have been directed toward extending these technologies for low temperature applications for wider applicability and portability [15][16][17][18][19][20][21][22] , as seen in Fig. 1a, which shows the state of the art conductivities of different solid oxides.…”

We use machine learning tools for the design and discovery of ABO3-type perovskite oxides for various energy applications, using over 7000 data points from the literature. We demonstrate a robust learning framework for efficient and accurate prediction of total conductivity of perovskites and their classification based on the type of charge carrier at different conditions of temperature and environment. After evaluating a set of >100 features, we identify average ionic radius, minimum electronegativity, minimum atomic mass, minimum formation energy of oxides for all B-site, and B-site dopant ions of the perovskite as the crucial and relevant predictors for determining conductivity and the type of charge carriers. The models are validated by predicting the conductivity of compounds absent in the training set. We screen 1793 undoped and 95,832 A-site and B-site doped perovskites to report the perovskites with high conductivities, which can be used for different energy applications, depending on the type of the charge carriers.
