The potential application of electrochemically formed copper sulfide as horseradish peroxidase mediator in the enzymatic biofuel cell and anthraquinone AV109 dye as a fuel is investigated. The open circuit voltage of 0.52 V and short circuit current of similar to 3.6 mu A/cm(2) are obtained, with the maximum specific power of similar to 1 mu W/cm(2). The influence of internal resistance of the cell is discussed. Decolorization is investigated under open circuit potentials, and under external load of 3.31 k Omega conditions. In both cases, 40% of decolorization is achieved, but are three times faster under external load conditions. Specific energy during decolorization in such cell is estimated to 5 mWh/m(2). The possible mechanism of the power generation during decolorization of AV 109 dye is discussed.
