To date, enzymatic biofuel cells (EFCs) have attracted attention due to their potential to power medical devices implanted into human bodies; however, EFCs must overcome obstacles such as poor stability and low power output. This research investigated the potential advantages of using CNFs versus MWCNTs as the medium for electron transfer. The ultimate goal was to increase the current generated by effectively increasing the total surface area for immobilization. In our study, fuel cell electrodes were fabricated by depositing a PEI/CNT/GOx onto a GC electrode. Performance of the electrodes was characterized through CV tests and SEM analysis. Our results convincingly show that MWCNTs outperform CNFs and remain a good choice for further EFC research.
