A Study On A Sodium Hypochlorite Fuel Cell System

Abstract

The main objectives of this study are to develop sodium hypochlorite fuel cell system, to study the effect of different electrodes in sodium hypochlorite electrolyte and to obtain the optimum electrolyte solution at varying molarity. A 50 ml of 1.0, 2.0, 3.0 or 4.0 M NaOH and 50 ml of NaOCl were filled in into the beaker. The plates was immersed into the electrolyte solutions. The cathode are remain the same for all experiment which used lead (II) oxide while the varying of electrodes such as lead, aluminium, ferum and copper served as anodes. Alligator clip wire was connected from one of the plates to the multimeter and another wire from other plate to the multimeter. The data collected included the voltages and current. The data were presented as polarization graphs where potential voltage is displayed on the x- axis and time on the y-axis. Each electrode materials and each electrolyte solutions were performed in triplicate and the data averaged. Thus, it can be concluded that that 3.0 M NaOH concentration of six-cell cell is better than single cell when the full-cell testing was performed. It can be summarized that 3.0 M NaOH concentration is the optimum parameter while the lead and lead (II) oxide electrodes is the best parameter operating based on the voltage when connected with the electrolyes solution.
