Fully enzymatic mediatorless fuel cell with efficient naphthylated carbon nanotube-laccase composite cathodes

Abstrakt

An efficient, mediator-free enzymatic glucose/O2 biofuel cell with an oxygen intensive anode based on glucose dehydrogenase is presented. In the device,the power of the biofuel cell and electrode potentials of each of the enzymatic electrodes were monitored in parallel under the biofuel cell working conditions. The carbon nanotube composite biocathode demonstrates an almost constant electrode potential vs. saturated calomel electrode under changing loads of the biofuel, even when relatively high current flows through the circuit. The fuel cell reveals good stability in time and is more powerful than other enzymatic film based biofuel cells; the power densities were 131+- 4uW/cm-1 at 300mV.
