Glucose-driven fuel cell constructed from enzymes and filter paper

A glucose-driven enzymatic filter-paper fuel cell is described. A strip of filter paper coated with carbon nanotubes and the glucose oxidase enzyme functions as the anode of the enzyme fuel cell. Another strip of filter paper coated with carbon nanotubes and the laccase enzyme functions as the cathode. Between the anode and the cathode, a third strip of filter paper is placed that holds the glucose, which is the fuel, and that allows the transport of ions. The design of the cell is simple, and all the materials used for the construction are readily available and biocompatible. The cell utilizes the oxidation of glucose to generate electricity and is useful to demonstrate how chemical energy can be converted to electrical energy.
