A new technique of lower electricity consumption electrolysis producing H2 has been developed

and the factors affecting producing H2 production were investigated. The results found that under the same electrolysis conditions

H2 production on the cathode increased with increasing electrolyte solution alkalinity; but decreased with increasing zinc ion concentration in the electrolyte solution. The results also revealed that H2 production on the cathode fluctuated with increasing electrolysis voltage

and reached a maximum when the voltage was at 0. 6 V. In a certainty range

it would be favorable to reduce the electricity consumption in H2 production with increasing electrolyte solution alkalinity; but the electricity consumption would be increase when electrolysis voltage was higher. Compared with producing H2 from H2O

the electrolysis voltage was lower by about IV

and the electricity consumption of H2 also decreased by 50% .
