If you don't want the HCl off-gassing, you need to circulate some water into the far left cell to keep the concentration from going too far. As you're adding fresh water, you're removing a little bit of what you're going to store as HCl in water.

I realize I probably did a shit job of describing that purification cell. So here's a picture (1). Salt goes in the middle, and then there's a stack of cation exchange membranes going toward the left, and a stack of anion exchange membranes going to the right. How to make these is in the YT video in the first post. Cl- heads left and Na+ heads right. At each membrane in the stack, the acidity / alkalinity increases until it eventually reaches the point where it starts either off-gassing HCl or precipitating NaOH, depending on which side you're looking at.
