Glucose can be used as an energy source for production of electricity in daily activities. Bio fuel cell systems can be consumed glucose as a fuel for electricity production. For doing that noble electrocatalysts must be used to facilitate glucose oxidation in anode. Gold and platinum nanoparticles on carbon Vulcan (Au-Pt/ C) are synthesized at various ratios (20:80, 40:60, 50:50, 60:40, 80:20) as the catalyst for the anodic oxidation of glucose for use in a direct glucose alkaline fuel cell (DGAFC). Characterization of the catalyst is carried out using physical and electrochemical methods. It is observed that gold nanoparticles are uniformly dispersed onto the carbon support. Linear Sweep Voltammetry was shown that the prepared Au-Pt/ C catalysts exhibit higher electro–catalytic activity for glucose oxidation than pure catalysts. The synergism effect in 50% platinum electrocatalyst in alloy form can provide the better performance for glucose oxidation in prepared electrocatalysts. It was confirmed by impedance spectroscopy results, also
