“…The suggested combinatorial DCA for current with two feedback and the STATCOM regulation approach leads to the most optimum outcome in comparison to other regulation approaches. The DCA is made utilizing the unscented Kalman filter technique 3 . In theory, the suggested regulation approach can make it possible to electronically control the power systems working with chemical substances.…”

Summary A new dynamic condition approximation method, which provides the current feedback, in collaboration with STATCOM regulation approach is presented to diminish the variation in voltage of solid oxide fuel cell (SOFC) electrical energy generators in connection to the compound power network in the time of faults. The suggested regulation approach is contrasted with the other present regulation techniques and the results show its advantage over the others in mitigating voltage fluctuation, inaccuracy and guarding the membranes inside the fuel cells. Because the dynamic internal conditions in the SOFC can precisely represent the transient conditions and dynamicity of the SOFC, their usage in designing the voltage regulator will provide more desirable control of voltage in the SOFC compared to the other approaches. Nonetheless, this model is not enough to mitigate AC voltage fluctuation which is caused by faults. Hence, STATCOM, which is a power electronic equipment, is applied to improve the alleviation of voltage variation and inaccuracy. Electricity network in the presence of the suggested regulation approach has shown stability in the linear assessments. Linear assessment of the system demonstrates that the final energy system embedded with the proposed regulation can maintain stability. Obtained numerical analysis demonstrates the validity of suggested approach.

“…What is particularly noteworthy is solid oxide electrolysis cell was mainly studied for its role in hydrogen production [2,3] in early years, and some electrolysis research related to CO 2 focused on the co-electrolysis of H 2 O/CO 2 [4][5][6][7][8][9], co-electrolysis is an effective way to produce syngas and has already been studied by experiment [10] and modeling [11]. It is complicated to analyze the principle of the co-electrolysis of H 2 O/ CO 2 thoroughly, as CO 2 is introduced into the reaction.…”

Solid oxide electrolysis cell (SOEC) is a device that can efficiently convert excessive power of renewable energy, such as wind or solar energy into chemical energy. High temperature CO 2 electrolysis based on solid oxide electrolysis cell has been proved as an effective method to produce sustainable fuels and reduce greenhouse emissions. The performance of cathodes as the place where the electrolysis reaction takes place for fuel gas affects the efficiency of SOEC, whereas traditional cathodes show relatively low catalytic activity towards CO 2 electrolysis. In recent years, in addition to the optimization of traditional Ni-based cathodes, the research on perovskite cathodes with better redox stability has been carried out rapidly. In this paper, the development of different cathodes of solid oxide electrolysis cell used for CO 2 electrolysis is summarized, from the study of new materials with different doping ratios for CO 2 electrolysis, to the microstructure optimization of electrode. It was found, that both durability and catalytic activity for the cathode materials could significantly improve the performance of single cells of SOEC. Finally, more prospects for future research work are put forward.

An integrated multiscale multiphysics framework to model solid oxide electrochemical cell systems is discussed. The framework directly couples electrode, single cell, stack, and system models using a hierarchical approach with minimal loss of information across the scales. The success of the model framework in better understanding solid oxide cells at the microscale and the industrial scale showcases it as a powerful tool for the rational design and upscaling of novel lab-scale materials and devices for next-generation chemical and electrochemical technologies.
