The invention provides a hydrogen leakage detection method and device for an electrolytic cell and the electrolytic cell. The hydrogen leakage detection method for the electrolytic cell comprises the steps that in the operation process of the electrolytic cell, the cell voltage of each electrolytic cell in the electrolytic cell is obtained; marking the electrolysis cell corresponding to the cell voltage as an abnormal electrolysis cell according to the condition that the cell voltage meets the voltage abnormal condition; after the electrolytic cell is shut down, electrochemical impedance detection is carried out on the abnormal electrolytic cell to obtain actual electrochemical impedance data; and according to the actual electrochemical impedance data, whether hydrogen leakage occurs in the abnormal electrolysis cell is judged. According to the hydrogen leakage detection method and device for the electrolytic cell and the electrolytic cell, by introducing an electrochemical impedance detection technology, a h
