Abstract


A simple energy harvesting strategy has been developed to selectively catalyze glucose in the presence of oxygen in a glucose/ O2 fuel cell. The anode consists of an abiotic catalyst Al/Au/ZnO, in which ZnO seed layer was deposited on the surface of Al/Au substrate using hydrothermal method. The cathode is constructed from a single rod of platinum with an outer diameter of 500 μm. Direct bioelectrocatalysis was demonstrated for the Al/Au/ZnO anode, which was evidence by the generation of anodic current in the presence of glucose. The abiotic glucose fuel cell was studied in phosphate buffer solution (pH 7.4) containing 5 mM glucose at a temperature of 22o C. The cell is characterized according to its open-circuit voltage, polarization profile and power density plot. The characteristics are comparable to biofuel cell utilizing a much more complex system design. Such low-cost light weight abiotic catalyzed glucose fuel cells have a great promise to be optimized & miniaturized to power bio-implantable devices.
