“…The essential characteristic of cathodes for SOFC is the porous structure, for example through the chemical reaction resulting advantage of shifting of electrons/ions and as well rises the length of triple phase boundary (TPB) [15]. Therefore, although both of the preparation methods resulted with materials with high porosities, the hydrothermal method was more successful.…”

Lanthanum strontium aluminum ferrite (La 0.8 Sr 0.2 Al 0.2 Fe 0.8 O 3±δ -LSAF) perovskites are drawing attention as cathodes in solid oxide fuel cells (SOFCs). The structural properties of these materials are mostly counting on the methods of preparation. In this study, two different preparation methods namely hydrothermal and sol-gel were applied to prepare LSAF perovskite. The characterization results including scanning electron microscopy (SEM), N 2 adsorption-desorption, and Fourier transform infrared spectroscopy (FT-IR) are investigated in detail. The results showed that the preparation method played an important role on the microstructure of the LSAFs. It can be highlighted that the hydrothermal method is more successful in obtaining quite small nanoparticles.

“…However, molten carbonate and solid oxide‐based fuel cells have operating temperature in the range of 600°C to 700°C and 600°C to 1000°C, respectively . The high‐temperature solid oxide‐based fuel cells are getting attention due to their application in micro combined heat and power systems to provide heat and power; however, their proper commercial availability lacks due to high operating temperature of the cell, and research is underway to reduce the operating temperature by investigating different materials to be used in micro combined power systems . They also have promising applications in aircraft and railway industries …”

Limitations, challenges, and solution approaches in grid‐connected renewable energy systems

Summary In the modern world, only conventional energy resources cannot fulfil the growing energy demand. Electricity is a fundamental building block of a technological revolution. Today, most of the electricity demand is met by the burning of fossil fuels but at the cost of adverse environmental impact. In order to bridge the gap between electricity demand and supply, nonconventional and eco‐friendly means of energy generation are considered. Renewable energy systems (RESs) offer an adequate solution to mitigate the challenges originated due to greenhouse gasses (GHG). However, they have an unpredictable power generation with specific site requirements. Grid integration of RESs may lead to new challenges related to power quality, reliability, power system stability, harmonics, subsynchronous oscillations (SSOs), power quality, and reactive power compensation. The integration with energy storage systems (ESSs) can reduce these complexities that arise due to the intermittent nature of RESs. In this paper, a comprehensive review of renewable energy sources has been presented. Application of ESSs in RESs and their development phase has been discussed. Role of ESSs in increasing lifetime, efficiency, and energy density of power system having RESs has been reviewed. Moreover, different techniques to solve the critical issues like low efficiency, harmonics, and inertia reduction in photovoltaic (PV) systems have been presented. Unlike most of the available review papers, this article also investigates the impact of FACTS technology in RESs‐based power system using multitype flexible AC transmission system (FACTS) controllers. Three simulation models have been developed in MATLAB/Simulink. The results show that FACTS devices help to maintain the stability of RESs integrated power system. This review paper is believed to be of potential benefit for researchers from both the industry and academia to develop better understanding of challenges and solution techniques for REs‐based power systems and future research dimensions in this area.

Interface Evolution of Solid Oxide Cells between the Electrode and the Interconnect Rib Induced with Applied Current

et al. 2022

Herein, the interface evolution of solid oxide cells (SOCs) on the interfacial contact resistance (ICR) between the electrode and the interconnect rib at different current densities is quantitatively studied using a stainless steel 430 (SUS430)/(La,Sr) (Co,Fe)O3 (LSCF)/SUS430 sandwich structure. To simulate the actual operation of SOCs, different current densities (200, 400, 600, 800, and 1000 mA cm−2) are applied to the sandwich structure by an external power supply and a DC electronic load. Experimental results show that, under an isothermal condition for 1012 h and a thermal cycling condition for 15 times, ICR is smaller when the current density is increased. This phenomenon may be due to the softening of the oxide film on the SUS430 interconnect rib and an increase in the contact area between the SUS430 interconnect rib and the electrode LSCF. Additionally, the microstructure, surface roughness, and contact theory are analyzed in detail. The results indicate that interface contact between the electrode and the interconnect rib may be improved with suitable applied current. This work provides the understanding of possible interface evolution of SOCs induced with applied current.
