Abstract EN
To increase the performance of photochemical fuel cells, nonequilibrium electrodeposition has been performed on Cu and Ni to make photosensitive anodes.
Processing parameters including electrolyte concentration, and electrode potential were studied using cyclic voltammetry.
Scanning electron microscopy (SEM) and X-ray Spectroscopy (EDS) were performed to understand the formation of the nanostructures during the nonequilibrium deposition of copper fractals.
An increase in the deposition rate was observed with the increase in electrolyte concentration (from 0.05 M to 1.0 M).
Similar trend was found when the cathode potential was decreased from −0.5 V to −4.5 V.
The effect of substrate material was also examined.
Porous fractal structures on copper were achieved, while the deposited material showed high density of surface cracks on nickel.
The fractal structures deposited on copper electrode with the increased surface area were converted into copper oxide by oxidation in air.
Such oxide samples were made into anodes for photochemical fuel cell application.
We demonstrated that an increase in the magnitude of open circuit output voltage is associated with the increase in the fractal surface area under the ultraviolet irradiation test conditions.
However, the electrodeposited fractals on nickel showed very limited increase in the magnitude of open circuit voltage.
