Abstract Details

2011, Master of Science, University of Toledo, Mechanical Engineering.
Fuel cells are one of the most promising technologies of the future which can be used to generate electricity using natural sources. With intent to increase the performance of a fuel cell, non-equilibrium electrodeposition is performed on the Cu and Ni electrode materials. The process parameters viz. electrolyte concentration, electrode potential and electrode material; governing the electrodeposition were studied using cyclic voltammetry, SEM image analysis and X-ray Spectroscopy (EDS) to understand their effect on the nanostructures deposited on these metals. An increase in the conductivity of the electrode is observed for an increase in electrolyte concentration (from 0.05 M to 1.0 M) and electrode potential (from -0.5 V to -4.5 V). The magnitude of reduction potential (Er) of the electrode was observed to increase in the range of 0.5 V to 1.3 V for the change in operating conditions. The effect of electrode material showed growth of porous fractal structures on copper and surface cracks on nickel. The fractal structures deposited on copper electrode improved the surface area of an electrode. The electrodeposited copper samples tested as cathode for fuel cell application showed an increase in magnitude of DC output voltage. However, electrodeposited nickel showed a decrease in the magnitude of DC output voltage.
