Figure 3 shows the hydrogen production rate changes with saline water concentrations at different input voltages. It illustrates that the increase in the concentration of saline water, the higher the hydrogen gas flow rates of hydrogen is obtained. The maximum hydrogen flow rate attained for sea water only. It gives H2 flow rates of 17.4, 26.6 and 43.1 cm3/min for input voltages of 20, 26 and 38 volts, respectively.
