Conductivity study of cassava starch coated anode for zinc-air fuel cell system

Abstract

In this study, cassava starch (CS) was prepared as conductive biodegradable material on zinc anode (ZnC) in zinc-air fuel cell (ZAFC) by using electrochemistry method. Successful formation of cassava on Zn anode was tested its conductivity by using four-point probe instrument and proven the enhancement of conductivity of anode after the deposition of CS. The optimization of conductivity study was further carried out in different concentrations of cassava. From conductivity analysis, it was shown the increment 30% of conductivity values from original conductivity of pure zinc. Moreover, scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) also were conducted to evaluate the morphology and chemical chain of cassava.
