Abstract: To provide a gas-liquid separator of a water electrolysis system, comprising: a liquid feeding atomizer and a gas-liquid separation chamber, wherein the liquid feeding atomizer includes a liquid feeding pressurized tube; and an atomizing spray head, in which the atomizing spray head converts a gas-liquid mixed liquor after pressurized by the liquid feeding pressurized tube into a mist droplet gas-liquid mixture. The gas-liquid separation chamber comprises a spiral flowing way, and the spiral flowing way extends the time that the mist droplet gas-liquid mixture spraying into the gas-liquid separation chamber flows downwards to the bottom of the gas-liquid separation chamber; an ultrasonic oscillation mechanism; a stirrer; an internal reservoir; and a filter mechanism, which performs the gas-liquid separation for unbroken bubbles in the mist droplet gas-liquid mixture through the pore difference.

Abstract: A method for preparing a large-area catalyst electrode includes the following steps: (A) providing an iron compound, a cobalt compound and a nickel compound, and dissolving these metal compounds in a solvent to form a mixed metal compound solution, and (B) providing a cathode and an anode, and performing a cathodic electrochemical deposition to the cathode, the anode and the mixed metal compound solution in a condition of constant voltage or constant current through a two-electrode method, followed by obtaining a catalyst electrode from the cathode. In the method for preparing the large-area catalyst electrode of the present invention, the large-area catalyst electrode having good dual-function water electrolysis catalytic property can be prepared by the steps of preparing the electrolyte, the electrochemical deposition, and the like. The process is simple and energy-saving.
