Perspective of Use of Pd/rGO in a Direct Urea Microfluidic Fuel Cell

The urine/urea oxidation reaction through catalysts with a higher performance in direct urea microfluidic fuel cells (DUµFC) is promising method for power generation due to the large amount of human and animal urine containing 2–2.5 wt% urea. This paper presents study that used as DUµFC presence palladium supported by reduced graphene oxide (rGO) generation. Some parameters, such urea, KOH H2SO4 concentration flux rate, among others, are optimized order carry out evaluation samples an air-breathing cell. results show Pd/rGo catalyst mixed Nafion® anodic compartment dispersed attached fibers, generating electrical contact giving rise reactions interest. In addition, XRD analysis confirmed successful deposition Pd rGo on substrate. These electrochemical promising, since, despite decrease general under ideal conditions respect normal cells, energy from was demonstrated.
