“…Among them, the RSOC module and the Li-ion battery module are constructed using basic mechanistic equations such as the Nernst equation, heat exchange, and electrochemical reflection combined with available heat-electricity-gas measurements for modeling and analysis. Zhang et al [38] set up three hybrid system operation scenarios to derive their RSOC/Li-ion battery hybrid system model. The proposed model was developed for the control needs of RSOC/Li-ion battery hybrid systems.…”

The application of new energy systems for industrial production to advance air pollution prevention and control has become an irreversible trend. This development includes hybrid systems consisting of reversible solid oxide cells (RSOC) and a Li-ion battery; however, at present the energy dispatching of such systems has an unstable factor in the form of poor heat/electricity/gas controllability. Therefore, the system studied in this paper uses the Li-ion battery as the energy supply/storage case, and uses the RSOC to supply power for the Li-ion battery charge or the Li-ion battery supply power to the RSOC for hydrogen production by water electrolysis. In this hybrid system, Li-ion battery thermoelectric safety and RSOC hydrogen production stability are extremely important. However, system operation involves the switching of multiple operating conditions, and the internal thermoelectric fluctuation mechanism is not yet clear. Therefore, in this paper we propose a separate control with a dual mode for hybrid systems. Active disturbance rejection control (ADRC) with a simple structure is used to achieve Li-ion battery module thermoelectric safety and control the hydrogen production/consumption of the RSOC module in the hybrid system. The results show that the required Li-ion battery thermoelectric safety and RSOC hydrogen consumption/production requirements can be met using the proposed controller, leading to a hybrid system with high stability control.

“…3,4 For example, the South Korean government has devoted significant efforts to increase the percentage of renewable energy in the total generated energy from 7 to 20%, and to reduce the carbon dioxide (CO 2 ) emissions from the projected 850.6 Million Tons of CO 2 equivalent (MtCO 2 eq) by 37% by 2030. 5 However, most of the renewable energy sources (including wind, solar, and other sources) depend on climate conditions and require advanced and high-effective technologies. 6,7 In the past decades, fuel cell technologies have attracted intensive attention as an additional form of renewable energy source for the future owing to its ability to directly generate electrical energy from the chemical reaction between H 2 and O 2 .…”

Currently, the energy crisis is considered one of the most important issues in developing and developed countries owing to increasing urbanization and industrialization. Proton exchange membrane (PEM) fuel cells are high-efficiency energy conversion devices that can replace fossil fuel energy systems. This study performed a multi-objective optimization to maximize cell performance and minimize pressure drop by optimizing four key design parameters (gas diffusion layer thickness, channel depth, channel width, and land width). To this end, the responses of the cell voltage and pressure drop of a PEM fuel cell model under different designs were investigated. First, the interactive effect of the design parameters on the cell voltage and pressure drop was investigated, and the results revealed that a simultaneous decrease in the land width and channel depth can have a beneficial effect on the cell voltage, whereas a simultaneous increase in the channel depth and channel width improves the pressure drop. Second-order polynomial equations were then derived to predict the cell voltage and pressure drop using the four design parameters. Finally, the comparison of the obtained optimal design and a reference cell design demonstrated the superior cell performance of the former with a lower pressure drop.

By Scopus, total19 literatures were listed and then excluded the system containing diesel plant, and the finalized as six papers (17)(18)(19)(20)(21)(22) are tabulated in Table 2. Al-Sharafi et al [17] evaluated the economic factor, LCOE as 1.208 $ kWh −1 in Abha area for the hydrogen production storage system, In the reference, the result of System #6 exhibits the minimum LCOE with 1.208 $ kWh −1 and LCOH is 43.3 $ kg −1 .…”

At 100% penetration, intermittent renewable energy causes outages. To flatten the leaping supply and demand curves of renewable energy, an energy storage medium and carrier are required. The Hydrogen energy stotrage system (HydESS), which combines a proton exchange membrane (PEM)-based water electrolysis (WE) system and a fuel cell (FC), has the quickest response time, the longest duration, and the greatest storage capacity. HOMER tools for techno-economic analysis are used to evaluate the HydESS hybrid system. Kyiv, Ukraine, is appealing due to its spatial-temporal wind speed, solar irradiance, and energy security. With an LCOE of $0.245 kWh−1 and 9.3% fuel cell power output, the most feasible solution is onshore wind turbine-coupled PEMFC HydESS. As a result 1,000-kW wind power, 250-kW PEMFC, 250-kW PEMWE, and 441-kW BESS are optimized to serve a 3,900 kWh day academic residence load. When compared to a diesel generator and a BESS, the hybrid HydESS reduces CO2 emissions by 4,132 tons over a 25-year period. The LCOE of a hybrid HydESS system is determined by the SOFC lifetime rather than the PEMFC's 2% difference between 40,000 and 50,000 h with the same rated power. This study recommends accelerating PEMFC development with fluctuation-endurable materials and design.
