Process structure for draining remaining stored water in electrolytic cell or electrolytic electrode assembly in water electrolysis device

Abstract

The invention discloses a process structure for draining remaining stored water in an electrolytic cell or an electrolytic electrode assembly in a water electrolysis device. The electrolytic cell is provided with a water inlet and a water outlet, the water outlet of the electrolytic cell can drain the water in the electrolytic electrode assembly, the water outlet of the electrolytic cell is higherthan a device electrolytic water output port in horizontal position, and thus the water in the electrolytic cell is possibly drained naturally from the water outlet; a ventilating part is provided with an air inlet communicating with the atmosphere and an air outlet communicating with the electrolytic cell or the water inlet of the electrolytic cell, and the ventilating part is a one-way ventilating part or a controlled one-way ventilating part; when the air pressure or the water pressure of the air outlet of the one-way ventilating part is lower than the air pressure of the air inlet, the one-way ventilating part is on, air can enter from the air inlet and can be output from the air outlet, and thus after water electrolysis work of the electrolytic cell and the electrolytic electrode assembly in the electrolytic cell is completed, the remaining stored water can be naturally drained from the device electrolytic water output port with the low horizontal position; and the work process that the controlled one-way ventilating part is controlled to conduct ventilating to drain the remaining stored water in the electrolytic cell is similar to the process.

In recent years, the membraneless water electrolysis technology has been invented, which diversifies the structure of electrolysis electrodes for electrolysis to produce hydrogen-rich water. A technical solution using activated carbon and foamed material electrodes has also emerged, which is conducive to improving the efficiency and indicators of electrolysis of water. However, the application People found that the electrolytic water electrodes, especially activated carbon and foamed material electrodes, have a certain charge capacity equivalent capacitance, which will be charged during the electrolytic water working process, and the charged electrode equivalent capacitance will be discharged when the electrolytic water work is over. Phenomenon, the water stored in the electrode assembly is electrolyzed in the direction of reverse electrolyzed water. The quality of the reversely electrolyzed water is poor, which will make the quality of the electrolyzed water output by the next electrolysis work worse, and the longer the time for reversely electrolyzed water stored in the electrode The quality of long water will be worse
