Abstract
Section titled āAbstractāNickel-modified boron-doped diamond (Ni-BDD) electrode was prepared to produce an electrical energy in a fuel cell. The electrode was prepared by electrodeposition from 1 mM Ni(NO3)2 in 0.1 M acetate buffer solution followed by repeated cycling in KOH. This electrode was then utilized to electrocatalyze the oxidation of urea in urine to produce electrical energy in a fuel cell. The use of Ni-BDD is expected to increase the activity of the fuel cell system. The catalytic performance was investigated by direct urea/hydrogen peroxide (H2O2) fuel cell. The result showed that a comparable potential of around 0.41 V could be achieved for one hour at room temperature when using Ni-BDD and Ni as the working electrode with a mixture of 0.01 mol Lā1 KOH and 0.33 mol Lā1 urea was used as the anolyte and a mixture of 2 mol Lā1 H2SO4 and 2 mol Lā1 H2O2 as the catholyte.
