This work describes EtOH,O2 membraneless enzymatic biofuel cells (EtOH,O2 MlessEBFCs) that employ laccase-based biocathodes and ADH/NAD+ bioanode. Laccase biocathodes were prepared by immobilizing a polypyrrole film containing different redox mediators (ruthenium and osmium complexes). The bioanode for EtOH,O2 MlessEBFCs was fabricated by immobilizing multiwalled carbon nanotubes, NAD+-dependent alcohol dehydrogenase enzyme (ADH), poly-methylene green, and poly(amidoamine) (PAMAM) dendrimer onto a carbon cloth platform. Maximum power density and current density were 21.0 ± 0.2 mW cm-2 and 0.15 ± 0.07 mA cm-2, respectively, in PBS (pH 6.5). Lifetime tests conducted for EtOH,O2 MlessEBFCs showed promising perspectives for their future application in miniaturized devices.

Cathodic Catalyst

A self-pumping enzymatic biofuel cell (self-pumping EBC) with a new cathodic catalyst which was modified by coating the mixture of carbon nanotubes/caffeic acid (CNTs/CA) on a carbon cloth (CC) to form a CNTs/CA/CC cathode electrode was fabricated. By using UV spectrophotometer, the absorbance of CA, CNTs, and the CNTs/CA composite was observed. To evaluate how the CNTs/CA/CC cathodic electrode improves the electrochemical performance of the self-pumping EBC, the measurement of the redox reaction current peak by cyclic voltammetry (CV) was implemented. In accordance with CV measurement, the utilization of the modified CNTs/CA/CC cathodic electrode exhibited a higher oxygen reduction current peak at 319.1μA under the saturated oxygen. The anode and cathode flow rates were 0.416μls−1 and 0.844 μls−1 which contribute to obtaining the capillary driven liquid efficiency as 30% for the former and 59% for the latter. Moreover, the self-pumping EBC performance tests showed that the maximum power density (MPD) of the self-pumping EBC with the modified cathodic electrode achieved 0.592 mWcm−2 which improved 10% in the performance compared with the bare CC electrode, 0.534 mWcm−2.

Modify Carbon

This paper proposes a simplified process that immobilizes enzymes onto carbon cloth electrodes to increase biofuel cell functionality. Polyethyleneimine (PEI) is used to modify carbon cloth electrodes to reduce the processing time and increase self-pumping enzymatic glucose biofuel cell (self-pumping EGBC) electricity. PEI is usually used in biochemical engineering gene transfection as GOx support to enhance enzyme immobilization. PEI is a good candidate for increasing enzymatic biofuel cell (EBC) redox current. PEI and GOx have been successfully immobilized onto carbon cloth electrodes through FT-IR analysis. A UV/Vis spectrophotometer was used to investigate the best PEI support concentration. PEI was proven to improve redox current by cyclic voltammetry analysis. The results show that the GOx/PEI electrode has excellent hydrophilicity on the GOx/PEI electrode surface using contact angle measurement. The optical and electrochemical analysis result shows that GOx/PEI was successfully immobilized onto carbon cloth electrodes. Experimental analysis showed that self-pumping EGBC achieved a power output of 0.609 mW/cm2 (126.9 mW/cm3). PEI contributes to the shortening of the process from a few hours to 5–10 minutes and enhances GOx fuel cell performance.
