There is a growing interest in solid oxide fuel cells (SOFCs) technology among the researchers a promising power generation with high energy efficiency, inflated fuel flexibility, and low environmental impact compared to conventional power generation systems. SOFCs are devices in which the chemical energy is directly converted into electrical energy with negligible emission. SOFCs have low pollution characteristics, high efficiency (~ 60%), and possess expanded fuel selection with little environmental effects. A single cell component of SOFCs is consisting an anode, cathode and an electrolyte which are stacked layer by layer to produce higher amount of power. The dense ceramic electrolyte transporting O2− ions and fills the space between the electrodes material. Redox reaction occurred at the electrodes side in the presence of fuels. The operating temperatures of SOFCs of 600–1200 °C which produced heat as a byproduct and fast electro-catalytic activity while using nonprecious metals. Many ceramic materials have been investigated for SOFCs electrolyte. Yttria-stabilized zirconia (YSZ) material was extensively used as dense electrolyte in SOFCs technology. In this review, the article presents; overview of the SOFCs devices and their related materials and mostly reviewed newly available reported.

“…15 One possible way to increase the cell stability when operating under high fuel utilization conditions is to use alternative materials or anodes impregnated with noble metal catalysts. 16,17 Their applicability has already been approved for small button cells, but has not yet been approved for the industrial-sized cells. For this reason, it is necessary to make a compromise between achieving high fuel utilization or high power.…”

“…As a new energy technology, anode supported planar solid oxide fuel cell (SOFC) has attracted much attention in recent years (Kong et al, 2016;Wang et al, 2018a;Wang et al, 2018b). Compared with other types of fuel cells, SOFC has the advantages of diversified fuel selection, high power generation efficiency, and no need for precious metal catalysis (Zheng et al, 2015;Presto et al, 2018;Zhang et al, 2018;Futamura et al, 2019;Hagen et al, 2019;Sahli et al, 2019). In order to further improve the performance of SOFC, a detailed understanding of its specific working process is required (Kong et al, 2020).…”

In this paper, a numerical model of gas flow, heat transfer, mass transfer and electrochemical reaction multi-physics field coupling of a planar SOFC is established and solved. According to the calculation results, the distribution of velocity, temperature and concentration inside the SOFC cell is analyzed. The influence of cathode inlet flow rate, porosity, rib width and other parameters on the performance of SOFC is also discussed. The results show that within a certain range, increasing the cathode inlet flow rate can significantly increase the average current density of the cell. Increasing the porosity of the electrode can improve the gas diffusion of the porous electrode, thereby increasing the rate of the electrochemical reaction. Increasing the width of the ribs will result in a significant decrease in cell performance. Therefore, the rib width should be reduced as much as possible within the allowable range to optimize the working performance of the cell.
