The super gravity field was applied to chlor-alkali electrolysis. The effects of super gravity on hydrogen evolution reaction (HER) and chlorine evolution reaction (CER) were investigated by linear sweep voltammetry, chronoamperometry and electrochemical impedance spectroscopy (EIS). The relationship between the cell voltages and gravity coefficient was studied. The results indicated that, the gas evolution reactions were intensified by super gravity and gas product was easier to spillover from solution. The solution resistance would reduce with the increase of gravity coefficient. The cell voltages also decreased with the increase of gravity coefficient, and the higher the current density, the larger the degree of cell voltage reduction.
