摘要: In this study, polyvinyl alcohol (PVA) is proposed as a new binder to improve the power output of microbial fuel cell. The physical and chemical properties PVA are characterized with Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), contact angle testing, density functional theory calculations, scanning electron microscopy (SEM). electrochemical performance an anode using carbon nanotubes electrocatalyst evaluated in Escherichia coli based cell chronoamperometry, impedance spectroscopy (EIS), polarization curve measurements, comparison made conventional binder, polytetrafluoroethylene (PTFE). It found that more hydrophilic has stronger interactions bacterial membrane than PTFE. Accordingly, facilitates formation biofilms thus exhibits improved transfer kinetics between bacteria compared MFC produces largest maximum power, 1.631 W m−2, which 97.9% greater one produced by PTFE (0.824 m−2).
