Title:
APPARATUS FOR PRODUCING HIGH-PRESSURE HYDROGEN AND OXYGEN BY USING WATER ELECTROLYSIS
Document Type and Number:
WIPO Patent Application WO/2022/071614
Kind Code:
A1
Abstract:
The objective of the present invention is to provide an electrochemical device and method for producing high-pressure hydrogen gas. An apparatus for producing and compressing high-pressure hydrogen gas and oxygen gas by using water electrolysis, according to the present invention, provides a method for improving the structural stability of a stack and a method for removing a trace amount of impurities generated when a porous polymer separator is used. To increase structural stability, the pressures inside and outside the stack are equalized, and the outside of the stack is wrapped with an integrated reinforcing agent. An electrochemical catalytic column is used to remove impurity gas by mixing, through the separator, hydrogen gas and oxygen gas produced by two electrodes inside the stack, and in order to make the pressures of the two gases equivalent, a method for adjusting the volume occupied by oxygen gas in the entire apparatus was adopted.
