description Nowadays demands for clean power source enhanced. Bio-fuel cell (BFC) can convert chemical energy to electrical energy. The enzyme-based biofuel cell (BFC) is a special fuel cell using enzyme as catalyst and can directly convert chemical energy to electrical energy. Bio-fuel cells are energy conversion devices based on bio-electrocatalysis leveraging on enzymes or microorganisms. Enzymatic fuel cells are promising low cost, compact and flexible energy resources. The basis of enzymatic fuel cells is transfer of electron from enzyme to the electrode surface and vice versa.. The DET of laccase enzyme has been studied using Multi-walled carbon nanotubes (MWCNTs)/Nafion polymer. Laccase was entrapped by nafion polymer . As Nafion is a proton exchange polymer but not an electron conductive, the MWCNTs were also used to facilitate electron transfer of laccase. Cyclic voltammetric results showed a well-defined redox peaks at 170 µA in a solution containing 10 µM o-dianisidine as a substrate for MWCNTs/Nafion composite. The cyclic voltammetric results showed that laccase immobilization on MWCNTs/Nafion is efficient. Therefore, this method can be used to fabricate biocathode of biofuels cellor laccase based biosensors.
