Hydrogen production gas-liquid separation system and hydrogen production system

The utility model provides a hydrogen production gas-liquid separation system and a hydrogen production system. The hydrogen-producing gas-liquid separation system comprises an electrolytic bath, a first gas-liquid separation device and a second gas-liquid separation device, the first separator group is communicated with an outlet of the electrolytic cell and can be used for carrying out gas-liquid separation on the first gas-liquid mixture to form a second gas-liquid mixture; the cooler group is communicated with an outlet of the first separator group and can cool the second gas-liquid mixture to form a third gas-liquid mixture; the second separator group is communicated with an outlet of the cooler group, the second separator group is constructed to be capable of carrying out gas-liquid separation on the third gas-liquid mixture and forming gas and liquid, and the particle size of liquid drops which can be separated by the second separator group is in a micron order. According to the technical scheme, the h
