摘要: Nano-Al2O3 is incorporated within the blend of sulfonated PVDF-co-HFP/Nafion in varying molar ratios for preparation nanocomposite membranes. A series tests namely, water uptake, swelling ratios, ion-exchange capacity (IEC), proton conductivity, oxygen diffusivity, etc. were conducted to analyze its capability a microbial fuel cell (MFC). The enhanced and diffusivity results observed with increasing nano-Al2O3 membrane. sample A5, containing 5 wt% nano-Al2O3, exhibited superior conductivity over naive SPVdF-co-HFP (∼88%) Nafion 115 membrane (∼3.5%). In addition, this prospective revealed comparable ion exchange reduced than corresponding 115. Furthermore, electrical efficiency particular was determined single chambered MFCs as constituent electrode assembly. Employing mixed Firmicutes biocatalysts, maximum power current density 541.52 ± 27 mW m−2 1900 95 mA from MFC, which an overall ∼48 11% increase With marked lowering impedance, indicate relevance Al2O3 filled separating barrier bio-energy conversion.
