ABSTRACT: Water electrolysis is considered as the most capable and old technology
for hydrogen fuel preparation. Electrolysis
needs external electrical energy through electrodes to split water into
hydrogen and oxygen. An efficient electrolysis requires suitable electrodes to
minimize potential drop. In this study Aluminium and Copper Coated Aluminium
were used as different combination of Anodes and Cathodes to find out more
efficient electrodes combination. NaCl solution in rain water was taken as
electrolyte. Rain water was taken to avoid ionic impedance of tap water and
expenses of distilled water. In this study, the most efficient electrode
combination was Copper Coated Aluminium (anode)-Aluminium
(cathode) and gave the highest efficiency of hydrogen production to about 11%
at normal temperature for very low concentration of NaCl (0.051 M)
which increased with temperature, up to 29% upon rising of temp to 60°C. It was showed that higher concentration of
electrolyte would surge the efficiency significantly. If the supplied heat
could be provided from any waste heat sources then this study would be more
efficient. However, current research evaluated the technical feasibility of
this electrode combination for producing hydrogen with electrolysis of rain
water utilizing electricity and modified electrodes.
