Electrolytic cell device, polar plate and polar frame

The utility model discloses an electrolytic bath device, a pole plate and a pole frame, and relates to the technical field of hydrogen production. The pole frame is a closed annular frame body, two groups of air outlet channels are formed in the top of the pole frame, each group comprises a plurality of air outlet channels, and the two groups of air outlet channels are respectively positioned on two sides of a vertical center line of the pole frame and are arranged in a staggered manner along the thickness direction of the pole frame; and the flow areas of the plurality of air outlet channels in the same group are reduced along the direction far away from the vertical center line. By utilizing different flow areas of the gas outlet channels in the same group, the flow areas of the gas outlet channels in the same group are reduced along the direction far away from the vertical center line of the pole frame, so that the difference of the quantity of gas-liquid mixtures entering different gas outlet channels is
