Efficiency of Aluminium and Copper Coated Aluminium Electrode in Hydrogen Fuel Generation from Rain Water

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.
