Hydrogen production system of electrolytic bath and scheduling method of hydrogen production system

The invention discloses an electrolytic cell hydrogen production system and a scheduling method thereof, and relates to the technical field of energy. The electrolytic cell hydrogen production unit comprises an alkaline electrolytic cell, three shell-and-tube heat exchangers and two gas-liquid separators; the heat recovery unit comprises two high-temperature heat storage tanks, three low-temperature heat storage tanks and a regional heating module; the first high-temperature heat storage tank provides heat for the third tubular heat exchanger in the hot standby stage of the alkaline electrolytic cell, meanwhile, the first high-temperature heat storage tank supplies heat to a region in the hydrogen production stage, and a medium used for region heating returns to the third low-temperature heat storage tank and then enters the second low-temperature heat storage tank; after being cooled to a proper temperature, the hydrogen enters the first low-temperature heat storage tank, so that circulation is completed, th
