AI Technical Summary
Technical Problem
In a high-pressure hydrogen system, when the liquid in the hydrogen separator is directly discharged into the oxygen separator, hydrogen will escape, reducing the purity of hydrogen in the oxygen and affecting the safe operation of the hydrogen production system.
Method used
The connection pipeline between the hydrogen separator and the oxygen separator is cancelled. After the liquid in the hydrogen separator is relieved by the gas-water separator, it participates in the electrolyte circulation through the water tank to reduce the solubility of hydrogen in the liquid and avoid hydrogen dissipation.
Benefits of technology
It improves the purity of hydrogen, ensures the safe operation of the hydrogen production system, and extends the service life of system parts.

Abstract
The embodiment of the invention provides an electrolyte circulating system of a high-pressure-difference proton exchange membrane electrolytic cell. The electrolyte circulating system comprises the electrolytic cell 1, an oxygen separator 2, a hydrogen separator 3, a water tank 4, a gas-water separator 5, an oxygen discharge system 6, a hydrogen discharge system 7, a heat exchanger 8, a resin tank 9, a circulating pump 10, a make-up pump 11 and a water circulating system 12. According to the operation condition of the high-pressure proton exchange membrane electrolytic cell, a communicating pipe between the hydrogen separator and the oxygen separator is omitted, the hydrogen separator is connected with the water tank through the gas-water separator, and the situation that excessive hydrogen escapes from liquid to enter the oxygen separator in the liquid discharging process of the hydrogen separator, and the purity of hydrogen in oxygen is reduced is avoided.
