This invention relates to the technical field of water electrolysis hydrogen production equipment, providing a T-type coupled gas-liquid separation and condensation integrated device and its working process for water electrolysis hydrogen production. The device includes a housing comprising a horizontal separation section, a vertical condensation section, and a liquid collection section.
