Abstract
Singlwalled carbon nanotubes (swcnts)covalently phenylated, napthylated or terphenylated were used for the construction of cathodes in a biobattery and in a biofuel cell. zn is the anode in the biobaterry and single-walled carbon nanotubes are covalently modified with glucose oxidase/catalase (swcnt-gox/cat) and the biofuel cell anode. the cell parameters were determined and the potentials of each of the electrodes under cell working conditions were simultaneously measured vs. ag/agcl reference electrode. this allowed to evaluate the changes of potential under changing loads of the fuel cell or biobaterry. a power density of ca.1mw/cm2 was achieved using the biobateryy with phenylated nanotubes at the cathode and the open circuit potential was 1,5v. the fully enzymatic fuel cell studeid had power density of 40uw/cm2 and at 20kohm loading. the power densities and working potentials are larger for the biobaterry which is especially useful for testing novel cathodes.
