Paper Abstract
Biofuel cells are a subset of fuel cells that employ biocatalysts. Enzyme-based biofuel cells (EBFCs) generate
electrical energy from biofuels such as glucose and ethanol, which are renewable and sustainable energy sources.
Glucose biofuel cells (GBFCs) are particularly interesting nowadays due to continuous harvesting of oxygen and
glucose from bioavailable substrates, activity inside the human body, and environmental benign, which generate
electricity through oxidation of glucose on the anode and reduction of oxygen on the cathode. Promoting the
electron transfer of redox enzymes at modified electrode utilizing Nano size materials, such as carbon nanotubes
(CNT), to achieve the direct electrochemistry of enzymes has been reported. The polypyrrole-MWCNTs-glucose
oxidase (PY-CNT-GOx) electrode has been investigated in the present work. Cyclic voltammetry tests were
performed in a three-electrode electrochemical set-up with modified electrode (Pt/PPy/MWCNTs/GOx) was used
as working electrode. Platinum flat and Ag/AgCl (saturated KCl) were used as counter electrode and the reference
electrode, respectively. The biofuel cells probe was prepared by immobilizing MWCNTs at the tip of a platinum
(Pt) electrode (0.5 cm2) with PPy as the support matrix We have demonstrated a well-dispersed nanomaterial
PPy/MWNT, which is able to immobilize GOx firmly under the condition of the absence of any other cross-linking
agent.
