... power curve further emphasizes this disparity, indicating a roughly threefold increase in power output for the SMS electrode compared to the CF electrode. Specific performance metrics are presented in Table 1. Notably, while the CF electrode exhibits a slightly higher open circuit voltage (E oc ), the SMS electrode delivers a superior current density and cell voltage, leading to enhanced overall performance. ...Context 2
... Ir is the "lost voltage" or overpotentials Table 1 demonstrate that under identical polarization conditions, the charge storability of the SMS electrode surpasses that of the CF electrode. This suggests an enhanced internal charge storage capacity within the MFC equipped with the SMS electrode. ...Similar publications

Perovskite layer structured (PLS) oxides exhibit some novel physical properties, such as ultrahigh-temperature piezoelectricity, semiconductivity, and oxygen ionic transport. However, synthesizing 5-layer PLS oxides, such as Sr5Nb5O17 ceramics, using traditional solid-state reaction methods is challenging due to their low phase stability. In this s...

Microbial fuel cell (MFC), a clean and promising technology that has the potential to tackle both environmental degradation and the global energy crisis, receives tremendous attention from researchers over recent years. The performance of each system component, including the membrane and electrode utilized in MFCs, has a great effect on the efficiency of converting chemical energy found in organic waste to power generation through bacterial metabolism. The MFCs have diverse applications that are growing day by day in developed countries. This review discusses recently available various potential applications including wastewater treatment, biohydrogen production, hazardous waste removal, generation of bioelectricity, robotics, biosensors, etc. There are still several challenges (e.g., system complexity, economic, commercialization, and other operational factors) for large‐scale practical applications, particularly for relatively low power output and delayed start‐up time, which is also reported in this review article. Moreover, the operational factors (e.g., electrode materials, proton exchange system, substrate, electron transfer mechanism, pH, temperature, external resistance, and shear stress and feed rate) that affect the performance of MFCs, are discussed in detail. To resolve these issues, optimizations of various parameters are also presented. In the previously published studies, this paper indicates that MFCs have demonstrated power densities ranging from 2.44 to 3.31 W m⁻², with Coulombic efficiencies reaching up to 55.6% under optimized conditions. It is also reported that MFCs have achieved the removal efficiency of chemical oxygen demand (COD), total organic carbon (TOC), and antibiotics up to 93.7%, 70%, and 98%, respectively. Finally, this paper highlights the future perspective of MFCs for full‐scale applications.
