“…These parameters are very influential because they have the effect of circulating the fuel cell electrolyte ions in SOFC to react to produce electricity. The flow of these ions is greatly influenced by the ionic conductivity of the electrolyte material used, so the selection of the appropriate electrolyte material is an important factor [4]. Each electrolyte material has a different composition and performance in the ion flow, which will affect electrical energy production.…”

SOFC solid electrolytes are known for their ionic conductivity characteristics, which increase with increasing SOFC operating temperature. Using COMSOL Multiphysics numerical simulation, analysis of SOFC power performance with yttria-stabilized zirconia (YSZ) and lithium sodium carbonate – gadolinium-doped ceria ({LiNa}2CO3-GDC) electrolytes was conducted to determine the potential of these electrolytes in their application in SOFC. The ionic conductivity of YSZ was differentiated based on the mole value of the yttria content, namely 8, 8.95, 10 and 11.54 mol. Meanwhile, GDC varied based on the (LiNa)2CO3 content such as 7.8, 10, 16.8 and 30 %. With the numerical model, the calculation error is an average of 7.32 % and 6.89 % for the experimental power and voltage values. In SOFC with the YSZ electrolyte, it was found that the power output can increase 26.4–35 times with an increase in operating temperature from 500 °C to 750 °C. SOFC with 8YSZ can produce the highest power compared to other YSZ, which is 123 A/m2 at a current of 198 A/m2 with an operating temperature of 500 °C and 3,440 A/m2 at a current of 5,549 A/m2 with an operating temperature of 750 °C. Whereas in SOFC with the GDC electrolyte, it was found that the power output can increase 18.6–22.6 times with an increase in operating temperature from 500 °C to 750 °C. SOFC with 30 % (LiNa)2CO3-GDC produced the highest power compared to other GDC, which is 231 A/m2 at a current of 444 A/m2 with an operating temperature of 500 °C and 5,240 A/m2 at a current of 10,077 A/m2 with an operating temperature of 750 °C. YSZ also showed the potential for an increase in power output as the SOFC temperature increases above 750 °C, while the 30 % variation (LiNa)2CO3-GDC shows a limited increase in ionic conductivity at 750 °C

“…SOFCs present several advantages over other types of fuel cells. These are related to the flexibility in the selection of the fuel, the ability to operate SOFCs directly on practical hydrocarbon fuels, and the higher overall efficiency [9]. The fact that the range of operating temperature is between 600-1000 • C allows SOFCs to use conventional thermal cycles to yield enhanced thermal efficiency and to extract hydrogen from a variety of fuels.…”

“…The fact that the range of operating temperature is between 600-1000 • C allows SOFCs to use conventional thermal cycles to yield enhanced thermal efficiency and to extract hydrogen from a variety of fuels. This type of fuel cell is tolerant to carbon monoxide (CO), which is electrochemically oxidized to CO 2 at the anode in opposition to PEM fuel cells, which are highly sensitive to CO poisoning [9][10][11]. SOFCs also have greater tolerance to impurities in the fuel, such as sulfur (as hydrogen sulfide, H 2 S, and carbonyl sulfide, COS), and to changes in the fuel composition such that fuel processing conditions are less strict [9,12].…”

The solid oxide fuel cell (SOFC) has become a promising energy conversion technology due to its high efficiency and low environmental impact. Though there are several reviews on the topic of SOFCs, comprehensive reports that simultaneously combine the latest developments in materials and integration strategies are very limited. This paper not only addresses those issues but also discusses the SOFCs working principles, design types, the fuels used, and the required features for electrodes and electrolytes. Furthermore, the implementation of this type of fuel cell on a commercial scale is analyzed. It is concluded that decreasing the SOFCs working temperature can reduce some of its current constraints, which will have a positive impact on SOFCs commercialization. Considering that SOFCs are already being successfully implemented in combined heat and power systems and off-grid power generation, the current status and prospects of this technology are thoroughly discussed.

Apatite‐type rare earth silicate with high oxygen ion conductivity are attractive materials for their wide potential applications, such as being used in solid oxide fuel cells as electrolytes. Herein, a series of new apatite‐type oxide ion conductors Ce9.33+xSi6O26+δ (x = 0.43, 0.67, 1.03) have been prepared, with their phases, stabilities, electrical properties, and conducting mechanisms been thoroughly studied. The results reveal that these materials are stable under inert or reducing atmospheres, but decomposed under an oxidizing environment at elevated temperatures. The combined alternative current and directive current techniques reveal dominating oxide ion conductions and minor electronic conductions in them. The bond‐valence‐based method is applied to investigate the possible oxide ion migration pathways and disclose the main contribution from interstitial oxygens, which locate between two neighboring tetrahedral SiO4 units and enable the oxide ion transporting among them along the c‐axis direction, whereas the intrinsic channel oxygens show an inferior responsibility for the oxide ion conductivities.
