Probing the Efficiency of PPMG-Based Composite Electrolytes for Applications of Proton Exchange Membrane Fuel Cell

Transactions of Tianjin University, Journal Year: 2024, Volume and Issue: 30(3), P. 262 - 283

Published: June 1, 2024

Abstract PPMG-based composite electrolytes were fabricated via the solution method using polyvinyl alcohol and polyvinylpyrrolidone blend reinforced with various contents of sulfonated inorganic filler. Sulfuric acid was employed as sulfonating agent to functionalize external surface filler, i.e., graphene oxide. The proton conductivities newly prepared exchange membranes (PEMs) increased by increasing temperature content oxide (SGO), ranging from 0.025 S/cm 0.060 S/cm. induction optimum level SGO is determined be an excellent route enhance ionic conductivity. single-cell performance test conducted sandwiching PEMs between anode (0.2 mg/cm 2 Pt/Ru) a cathode Pt) prepare membrane electrode assemblies, followed hot pressing under pressure approximately 100 kg/cm at 60 °C for 5–10 min. highest power densities achieved PPMG 14.9 35.60 mW/cm 25 70 °C, respectively, ambient 100% relative humidity. Results showed that exhibit good electrochemical performance. results indicated 6 wt% filler can used alternative applications high-performance fuel cell.

Recent Applications, Challenges, and Future Prospects of Microbial Fuel Cells: A Review

Global Challenges, Journal Year: 2025, Volume and Issue: unknown

Published: April 16, 2025

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