Abstract: 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% .
