Customizable Fishbone Lamella Gas Seperation Grid for Electrolysis

This is a halve grid for gas separation in an electrolysis apparatus.
When two (mirrored versions) of these are put together back on back the lamellas form herringbone shapes. This disallows the gasses to pass from one side to the other and mix.
.
In a concrete application a gas separation wall must be extended upwards and the fluid level must be always kept above the grid.
Standalone this thing is incomplete. An electrolysis chamber capable of gas separation is needed in conjunction. It
