Abstract

Urea as one of the most abundant compounds that can be used as a fuel in fuel cells. It contains a nitrogen-hydrogen bond that can easily be broken by electrochemical processes to produce two molecules of hydrogen. The hydrogen released can generate electricity as in a fuel cell. In this research, boron-doped diamond (BDD) was modified using nickel and/or cobalt electrodeposition to provide Ni-Co-BDD, Ni-BDD, and Co-BDD working electrodes for enhanced urea electro-oxidation. The highest power density and potential was achieved using Ni-Co-BDD (96.4 mW cm^-2 and 0.92 V, respectively), while the highest current density was achieved using Co-BDD (165.34 mA cm^-2). Overall, the results indicate that the best and most stable electrode for fuel cells is that based on Ni-Co-BDD.
